Summary
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The mod_rewrite module uses a rule-based rewriting
|
|
Packit |
90a5c9 |
engine, based on a PCRE regular-expression parser, to rewrite requested URLs on
|
|
Packit |
90a5c9 |
the fly. By default, mod_rewrite maps a URL to a filesystem
|
|
Packit |
90a5c9 |
path. However, it can also be used to redirect one URL to another URL, or
|
|
Packit |
90a5c9 |
to invoke an internal proxy fetch.
|
|
Packit |
90a5c9 |
mod_rewrite provides a flexible and powerful way to
|
|
Packit |
90a5c9 |
manipulate URLs using an unlimited number of rules. Each rule can have an
|
|
Packit |
90a5c9 |
unlimited number of attached rule conditions, to allow you to rewrite URL
|
|
Packit |
90a5c9 |
based on server variables, environment variables, HTTP headers, or time
|
|
Packit |
90a5c9 |
stamps.
|
|
Packit |
90a5c9 |
mod_rewrite operates on the full URL path, including the
|
|
Packit |
90a5c9 |
path-info section. A rewrite rule can be invoked in
|
|
Packit |
90a5c9 |
httpd.conf or in .htaccess. The path generated
|
|
Packit |
90a5c9 |
by a rewrite rule can include a query string, or can lead to internal
|
|
Packit |
90a5c9 |
sub-processing, external request redirection, or internal proxy
|
|
Packit |
90a5c9 |
throughput.

|
|

mod_rewrite offers detailed logging of its actions
|
|
Packit |
90a5c9 |
at the trace1 to trace8 log levels. The
|
|
Packit |
90a5c9 |
log level can be set specifically for mod_rewrite
|
|
Packit |
90a5c9 |
using the LogLevel directive: Up to
|
|
Packit |
90a5c9 |
level debug, no actions are logged, while trace8
|
|
Packit |
90a5c9 |
means that practically all actions are logged.

Using a high trace log level for mod_rewrite
|
|
Packit |
90a5c9 |
will slow down your Apache HTTP Server dramatically! Use a log
|
|
Packit |
90a5c9 |
level higher than trace2 only for debugging!

Those familiar with earlier versions of
|
|
Packit |
90a5c9 |
mod_rewrite will no doubt be looking for the
|
|
Packit |
90a5c9 |
RewriteLog and RewriteLogLevel
|
|
Packit |
90a5c9 |
directives. This functionality has been completely replaced by the
|
|
Packit |
90a5c9 |
new per-module logging configuration mentioned above.

The RewriteBase directive specifies the
|
|
Packit |
90a5c9 |
URL prefix to be used for per-directory (htaccess)
|
|
Packit |
90a5c9 |
RewriteRule directives that
|
|
Packit |
90a5c9 |
substitute a relative path.
|
|
Packit |
90a5c9 |
This directive is required when you use a relative path
|
|
Packit |
90a5c9 |
in a substitution in per-directory (htaccess) context unless any
|
|
Packit |
90a5c9 |
of the following conditions are true:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The original request, and the substitution, are underneath the
|
|
Packit |
90a5c9 |
DocumentRoot
|
|
Packit |
90a5c9 |
(as opposed to reachable by other means, such as
|
|
Packit |
90a5c9 |
Alias).
|
|
Packit |
90a5c9 |
The filesystem path to the directory containing the
|
|
Packit |
90a5c9 |
RewriteRule,
|
|
Packit |
90a5c9 |
suffixed by the relative
|
|
Packit |
90a5c9 |
substitution is also valid as a URL path on the server
|
|
Packit |
90a5c9 |
(this is rare).
|
|
Packit |
90a5c9 |
In Apache HTTP Server 2.4.16 and later, this directive may be
|
|
Packit |
90a5c9 |
omitted when the request is mapped via
|
|
Packit |
90a5c9 |
Alias
|
|
Packit |
90a5c9 |
or mod_userdir.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
In the example below, RewriteBase is necessary
|
|
Packit |
90a5c9 |
to avoid rewriting to http://example.com/opt/myapp-1.2.3/welcome.html
|
|
Packit |
90a5c9 |
since the resource was not relative to the document root. This
|
|
Packit |
90a5c9 |
misconfiguration would normally cause the server to look for an "opt"
|
|
Packit |
90a5c9 |
directory under the document root.
|
|
Packit |
90a5c9 |
DocumentRoot "/var/www/example.com"
|
|
Packit |
90a5c9 |
AliasMatch "^/myapp" "/opt/myapp-1.2.3"

The RewriteCond directive defines a
|
|
Packit |
90a5c9 |
rule condition. One or more RewriteCond
|
|
Packit |
90a5c9 |
can precede a RewriteRule
|
|
Packit |
90a5c9 |
directive. The following rule is then only used if both
|
|
Packit |
90a5c9 |
the current state of the URI matches its pattern, and if these conditions are met.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
TestString is a string which can contain the
|
|
Packit |
90a5c9 |
following expanded constructs in addition to plain text:

RewriteRule backreferences: These are
|
|
Packit |
90a5c9 |
backreferences of the form $N
|
|
Packit |
90a5c9 |
(0 <= N <= 9). $1 to $9 provide access to the grouped
|
|
Packit |
90a5c9 |
parts (in parentheses) of the pattern, from the
|
|
Packit |
90a5c9 |
RewriteRule which is subject to the current
|
|
Packit |
90a5c9 |
set of RewriteCond conditions. $0 provides
|

Packit |
90a5c9 |
access to the whole string matched by that pattern.

Packit |
90a5c9 |
backreferences of the form %N
|
|
Packit |
90a5c9 |
(0 <= N <= 9). %1 to %9 provide access to the grouped
|

|
|
Packit |
90a5c9 |

|
Packit |
90a5c9 |
API_VERSION
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
This is the version of the Apache httpd module API
|
|
Packit |
90a5c9 |
(the internal interface between server and
|
|
Packit |
90a5c9 |
module) in the current httpd build, as defined in
|
|
Packit |
90a5c9 |
include/ap_mmn.h. The module API version
|
|
Packit |
90a5c9 |
corresponds to the version of Apache httpd in use (in
|
|
Packit |
90a5c9 |
the release version of Apache httpd 1.3.14, for
|
|
Packit |
90a5c9 |
instance, it is 19990320:10), but is mainly of
|
|
Packit |
90a5c9 |
interest to module authors.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
CONN_REMOTE_ADDR
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Since 2.4.8: The peer IP address of the connection (see the
|
|
Packit |
90a5c9 |
mod_remoteip module).
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
HTTPS
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Will contain the text "on" if the connection is
|
|
Packit |
90a5c9 |
using SSL/TLS, or "off" otherwise. (This variable
|
|
Packit |
90a5c9 |
can be safely used regardless of whether or not
|
|
Packit |
90a5c9 |
mod_ssl is loaded).
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
IS_SUBREQ
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Will contain the text "true" if the request
|
|
Packit |
90a5c9 |
currently being processed is a sub-request,
|
|
Packit |
90a5c9 |
"false" otherwise. Sub-requests may be generated
|
|
Packit |
90a5c9 |
by modules that need to resolve additional files
|
|
Packit |
90a5c9 |
or URIs in order to complete their tasks.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
REMOTE_ADDR
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The IP address of the remote host (see the
|
|
Packit |
90a5c9 |
mod_remoteip module).
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
REQUEST_FILENAME
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The full local filesystem path to the file or
|
|
Packit |
90a5c9 |
script matching the request, if this has already
|
|
Packit |
90a5c9 |
been determined by the server at the time
|
|
Packit |
90a5c9 |
REQUEST_FILENAME is referenced. Otherwise,
|
|
Packit |
90a5c9 |
such as when used in virtual host context, the same
|
|
Packit |
90a5c9 |
value as REQUEST_URI. Depending on the value of
|
|
Packit |
90a5c9 |
AcceptPathInfo, the
|
|
Packit |
90a5c9 |
server may have only used some leading components of the
|
|
Packit |
90a5c9 |
REQUEST_URI to map the request to a file.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
REQUEST_SCHEME
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Will contain the scheme of the request (usually
|
|
Packit |
90a5c9 |
"http" or "https"). This value can be influenced with
|
|
Packit |
90a5c9 |
ServerName.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
REQUEST_URI
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The path component of the requested URI,
|
|
Packit |
90a5c9 |
such as "/index.html". This notably excludes the
|
|
Packit |
90a5c9 |
query string which is available as its own variable
|
|
Packit |
90a5c9 |
named QUERY_STRING.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
THE_REQUEST
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The full HTTP request line sent by the
|
|
Packit |
90a5c9 |
browser to the server (e.g., "GET
|
|
Packit |
90a5c9 |
/index.html HTTP/1.1"). This does not
|
|
Packit |
90a5c9 |
include any additional headers sent by the
|
|
Packit |
90a5c9 |
browser. This value has not been unescaped
|
|
Packit |
90a5c9 |
(decoded), unlike most other variables below.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
If the TestString has the special value expr,
|
|
Packit |
90a5c9 |
the CondPattern will be treated as an
|
|
Packit |
90a5c9 |
ap_expr. HTTP headers referenced in the
|
|
Packit |
90a5c9 |
expression will be added to the Vary header if the novary
|
|
Packit |
90a5c9 |
flag is not given.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Other things you should be aware of:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The variables SCRIPT_FILENAME and REQUEST_FILENAME
|
|
Packit |
90a5c9 |
contain the same value - the value of the
|
|
Packit |
90a5c9 |
filename field of the internal
|
|
Packit |
90a5c9 |
request_rec structure of the Apache HTTP Server.
|
|
Packit |
90a5c9 |
The first name is the commonly known CGI variable name
|
|
Packit |
90a5c9 |
while the second is the appropriate counterpart of
|
|
Packit |
90a5c9 |
REQUEST_URI (which contains the value of the
|
|
Packit |
90a5c9 |
uri field of request_rec).
|
|
Packit |
90a5c9 |
If a substitution occurred and the rewriting continues,
|
|
Packit |
90a5c9 |
the value of both variables will be updated accordingly.
|
|
Packit |
90a5c9 |
If used in per-server context (i.e., before the
|
|
Packit |
90a5c9 |
request is mapped to the filesystem) SCRIPT_FILENAME and
|
|
Packit |
90a5c9 |
REQUEST_FILENAME cannot contain the full local filesystem
|
|
Packit |
90a5c9 |
path since the path is unknown at this stage of processing.
|
|
Packit |
90a5c9 |
Both variables will initially contain the value of REQUEST_URI
|
|
Packit |
90a5c9 |
in that case. In order to obtain the full local filesystem
|
|
Packit |
90a5c9 |
path of the request in per-server context, use an URL-based
|
|
Packit |
90a5c9 |
look-ahead %{LA-U:REQUEST_FILENAME} to determine
|
|
Packit |
90a5c9 |
the final value of REQUEST_FILENAME.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
%{ENV:variable}, where variable can be
|
|
Packit |
90a5c9 |
any environment variable, is also available.
|
|
Packit |
90a5c9 |
This is looked-up via internal
|
|
Packit |
90a5c9 |
Apache httpd structures and (if not found there) via
|
|
Packit |
90a5c9 |
getenv() from the Apache httpd server process.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
%{SSL:variable}, where variable is the
|
|
Packit |
90a5c9 |
name of an SSL environment
|
|
Packit |
90a5c9 |
variable, can be used whether or not
|
|
Packit |
90a5c9 |
mod_ssl is loaded, but will always expand to
|
|
Packit |
90a5c9 |
the empty string if it is not. Example:
|
|
Packit |
90a5c9 |
%{SSL:SSL_CIPHER_USEKEYSIZE} may expand to
|
|
Packit |
90a5c9 |
128. These variables are available even without
|
|
Packit |
90a5c9 |
setting the StdEnvVars option of the
|
|
Packit |
90a5c9 |
SSLOptions directive.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
%{HTTP:header}, where header can be
|
|
Packit |
90a5c9 |
any HTTP MIME-header name, can always be used to obtain the
|
|
Packit |
90a5c9 |
value of a header sent in the HTTP request.
|
|
Packit |
90a5c9 |
Example: %{HTTP:Proxy-Connection} is
|
|
Packit |
90a5c9 |
the value of the HTTP header
|
|
Packit |
90a5c9 |
``Proxy-Connection:''.
|
|
Packit |
90a5c9 |
If a HTTP header is used in a condition this header is added to
|
|
Packit |
90a5c9 |
the Vary header of the response in case the condition evaluates
|
|
Packit |
90a5c9 |
to true for the request. It is not added if the
|
|
Packit |
90a5c9 |
condition evaluates to false for the request. Adding the HTTP header
|
|
Packit |
90a5c9 |
to the Vary header of the response is needed for proper caching.
|
|
Packit |
90a5c9 |
It has to be kept in mind that conditions follow a short circuit
|
|
Packit |
90a5c9 |
logic in the case of the 'ornext|OR' flag
|
|
Packit |
90a5c9 |
so that certain conditions might not be evaluated at all.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
%{LA-U:variable}
|
|
Packit |
90a5c9 |
can be used for look-aheads which perform
|
|
Packit |
90a5c9 |
an internal (URL-based) sub-request to determine the final
|
|
Packit |
90a5c9 |
value of variable. This can be used to access
|
|
Packit |
90a5c9 |
variable for rewriting which is not available at the current
|
|
Packit |
90a5c9 |
stage, but will be set in a later phase.
|
|
Packit |
90a5c9 |
For instance, to rewrite according to the
|
|
Packit |
90a5c9 |
REMOTE_USER variable from within the
|
|
Packit |
90a5c9 |
per-server context (httpd.conf file) you must
|
|
Packit |
90a5c9 |
use %{LA-U:REMOTE_USER} - this
|
|
Packit |
90a5c9 |
variable is set by the authorization phases, which come
|
|
Packit |
90a5c9 |
after the URL translation phase (during which
|
|
Packit |
90a5c9 |
mod_rewrite operates).
|
|
Packit |
90a5c9 |
On the other hand, because mod_rewrite implements
|
|
Packit |
90a5c9 |
its per-directory context (.htaccess file) via
|
|
Packit |
90a5c9 |
the Fixup phase of the API and because the authorization
|
|
Packit |
90a5c9 |
phases come before this phase, you just can use
|
|
Packit |
90a5c9 |
%{REMOTE_USER} in that context.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
%{LA-F:variable} can be used to perform an internal
|
|
Packit |
90a5c9 |
(filename-based) sub-request, to determine the final value
|
|
Packit |
90a5c9 |
of variable. Most of the time, this is the same as
|
|
Packit |
90a5c9 |
LA-U above.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
CondPattern is the condition pattern,
|
|
Packit |
90a5c9 |
a regular expression which is applied to the
|
|
Packit |
90a5c9 |
current instance of the TestString.
|
|
Packit |
90a5c9 |
TestString is first evaluated, before being matched against
|
|
Packit |
90a5c9 |
CondPattern.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
CondPattern is usually a
|
|
Packit |
90a5c9 |
perl compatible regular expression, but there is
|
|
Packit |
90a5c9 |
additional syntax available to perform other useful tests against
|
|
Packit |
90a5c9 |
the Teststring:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
You can prefix the pattern string with a
|
|
Packit |
90a5c9 |
'!' character (exclamation mark) to negate the result
|
|
Packit |
90a5c9 |
of the condition, no matter what kind of CondPattern is used.
|
|
Packit |
90a5c9 |

|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |

|
Packit |
90a5c9 |
You can perform lexicographical string comparisons:

does not return information about the status code the

whether or not it exists, and has executable permissions.

Packit |
90a5c9 |
These permissions are determined according to

90a5c9 |
the underlying OS.

90a5c9 |
For example:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
RewriteCond /var/www/%{REQUEST_URI} !-f
|
|

|
|
Packit |
90a5c9 |
If the TestString has the special value expr, the
|
|
Packit |
90a5c9 |
CondPattern will be treated as an
|
|
Packit |
90a5c9 |
ap_expr.

90a5c9 |
|
|
Packit |
90a5c9 |

In the below example, -strmatch is used to
|
|
Packit |
90a5c9 |
compare the REFERER against the site hostname,
|
|
Packit |
90a5c9 |
to block unwanted hotlinking.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
RewriteCond expr "! %{HTTP_REFERER} -strmatch '*://%{HTTP_HOST}/*'"
|
|
Packit |
90a5c9 |
RewriteRule "^/images" "-" [F]

|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
You can also set special flags for CondPattern by appending
|
|
Packit |
90a5c9 |
[flags]
|
|
Packit |
90a5c9 |
as the third argument to the RewriteCond
|
|
Packit |
90a5c9 |
directive, where flags is a comma-separated list of any of the
|
|
Packit |
90a5c9 |
following flags:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
'nocase|NC'
|
|
Packit |
90a5c9 |
(no case)
|
|
Packit |
90a5c9 |
This makes the test case-insensitive - differences
|
|
Packit |
90a5c9 |
between 'A-Z' and 'a-z' are ignored, both in the
|
|
Packit |
90a5c9 |
expanded TestString and the CondPattern.
|
|
Packit |
90a5c9 |
This flag is effective only for comparisons between
|
|
Packit |
90a5c9 |
TestString and CondPattern. It has no
|
|
Packit |
90a5c9 |
effect on filesystem and subrequest checks.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
'ornext|OR'
|
|
Packit |
90a5c9 |
(or next condition)
|
|
Packit |
90a5c9 |
Use this to combine rule conditions with a local OR
|
|
Packit |
90a5c9 |
instead of the implicit AND. Typical example:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
RewriteCond "%{REMOTE_HOST}" "^host1" [OR]
|
|
Packit |
90a5c9 |
RewriteCond "%{REMOTE_HOST}" "^host2" [OR]
|
|
Packit |
90a5c9 |
RewriteCond "%{REMOTE_HOST}" "^host3"
|
|
Packit |
90a5c9 |
RewriteRule ...some special stuff for any of these hosts...
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Without this flag you would have to write the condition/rule
|
|
Packit |
90a5c9 |
pair three times.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
'novary|NV'
|
|
Packit |
90a5c9 |
(no vary)
|
|
Packit |
90a5c9 |
If a HTTP header is used in the condition, this flag prevents
|
|
Packit |
90a5c9 |
this header from being added to the Vary header of the response.
|
|
Packit |
90a5c9 |
Using this flag might break proper caching of the response if
|
|
Packit |
90a5c9 |
the representation of this response varies on the value of this header.
|
|
Packit |
90a5c9 |
So this flag should be only used if the meaning of the Vary header
|
|
Packit |
90a5c9 |
is well understood.

|
|
Packit |
90a5c9 |
To rewrite the Homepage of a site according to the
|
|
Packit |
90a5c9 |
``User-Agent:'' header of the request, you can
|
|
Packit |
90a5c9 |
use the following:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
RewriteCond "%{HTTP_USER_AGENT}" "(iPhone|Blackberry|Android)"
|

Packit |
90a5c9 |
The RewriteEngine directive enables or
|
|
Packit |
90a5c9 |
disables the runtime rewriting engine. If it is set to
|
|
Packit |
90a5c9 |
off this module does no runtime processing at
|
|
Packit |
90a5c9 |
all. It does not even update the SCRIPT_URx
|
|
Packit |
90a5c9 |
environment variables.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Use this directive to disable rules in a particular context,
|
|
Packit |
90a5c9 |
rather than commenting out all the RewriteRule directives.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Note that rewrite configurations are not
|
|
Packit |
90a5c9 |
inherited by virtual hosts. This means that you need to have a
|
|
Packit |
90a5c9 |
RewriteEngine on directive for each virtual host
|
|
Packit |
90a5c9 |
in which you wish to use rewrite rules.

The RewriteMap directive defines a
|
|
Packit |
90a5c9 |
Rewriting Map which can be used inside rule
|
|
Packit |
90a5c9 |
substitution strings by the mapping-functions to
|
|
Packit |
90a5c9 |
insert/substitute fields through a key lookup. The source of
|
|
Packit |
90a5c9 |
this lookup can be of various types.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The MapName is
|
|
Packit |
90a5c9 |
the name of the map and will be used to specify a
|
|
Packit |
90a5c9 |
mapping-function for the substitution strings of a rewriting
|
|
Packit |
90a5c9 |
rule via one of the following constructs:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
${ MapName :
|
|
Packit |
90a5c9 |
LookupKey }
|
|
Packit |
90a5c9 |
${ MapName :
|
|
Packit |
90a5c9 |
LookupKey | DefaultValue
|
|
Packit |
90a5c9 |
}
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
When such a construct occurs, the map MapName is
|
|
Packit |
90a5c9 |
consulted and the key LookupKey is looked-up. If the
|
|
Packit |
90a5c9 |
key is found, the map-function construct is substituted by
|
|
Packit |
90a5c9 |
SubstValue. If the key is not found then it is
|
|
Packit |
90a5c9 |
substituted by DefaultValue or by the empty string
|
|
Packit |
90a5c9 |
if no DefaultValue was specified. Empty values
|
|
Packit |
90a5c9 |
behave as if the key was absent, therefore it is not possible
|
|
Packit |
90a5c9 |
to distinguish between empty-valued keys and absent keys.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
For example, you might define a
|
|
Packit |
90a5c9 |
RewriteMap as:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
RewriteMap examplemap "txt:/path/to/file/map.txt"
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
You would then be able to use this map in a
|
|
Packit |
90a5c9 |
RewriteRule as follows:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
RewriteRule "^/ex/(.*)" "${examplemap:$1}"
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The meaning of the MapTypeOptions argument depends on
|
|
Packit |
90a5c9 |
particular MapType. See the
|
|
Packit |
90a5c9 |
Using RewriteMap for
|
|
Packit |
90a5c9 |
more information.
|
|
Packit |
90a5c9 |

Packit |
90a5c9 |

The RewriteOptions directive sets some
|
|
Packit |
90a5c9 |
special options for the current per-server or per-directory
|
|
Packit |
90a5c9 |
configuration. The Option string can currently
|
|
Packit |
90a5c9 |
only be one of the following:
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Inherit
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
This forces the current configuration to inherit the
|
|
Packit |
90a5c9 |
configuration of the parent. In per-virtual-server context,
|
|
Packit |
90a5c9 |
this means that the maps, conditions and rules of the main
|
|
Packit |
90a5c9 |
server are inherited. In per-directory context this means
|
|
Packit |
90a5c9 |
that conditions and rules of the parent directory's
|
|
Packit |
90a5c9 |
.htaccess configuration or
|
|
Packit |
90a5c9 |
<Directory>
|
|
Packit |
90a5c9 |
sections are inherited. The inherited rules are virtually copied
|
|
Packit |
90a5c9 |
to the section where this directive is being used. If used in
|
|
Packit |
90a5c9 |
combination with local rules, the inherited rules are copied behind
|
|
Packit |
90a5c9 |
the local rules. The position of this directive - below or above
|
|
Packit |
90a5c9 |
of local rules - has no influence on this behavior. If local
|
|
Packit |
90a5c9 |
rules forced the rewriting to stop, the inherited rules won't
|
|
Packit |
90a5c9 |
be processed.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Rules inherited from the parent scope are applied

InheritBefore
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Like Inherit above, but the rules from the parent scope
|
|
Packit |
90a5c9 |
are applied before rules specified in the child scope.

If this option is enabled, all child configurations will inherit
|
|
Packit |
90a5c9 |
the configuration of the current configuration. It is equivalent to
|
|
Packit |
90a5c9 |
specifying RewriteOptions Inherit in all child
|

Packit |
90a5c9 |
configurations. See the Inherit option for more details

AllowNoSlash
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
By default, mod_rewrite will ignore URLs that map to a
|
|
Packit |
90a5c9 |
directory on disk but lack a trailing slash, in the expectation that
|
|
Packit |
90a5c9 |
the mod_dir module will issue the client with a redirect to
|
|
Packit |
90a5c9 |
the canonical URL with a trailing slash.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
When the DirectorySlash directive
|
|
Packit |
90a5c9 |
is set to off, the AllowNoSlash option can be enabled to ensure
|
|
Packit |
90a5c9 |
that rewrite rules are no longer ignored. This option makes it possible to
|
|
Packit |
90a5c9 |
apply rewrite rules within .htaccess files that match the directory without
|
|
Packit |
90a5c9 |
a trailing slash, if so desired.

Packit |

Packit |
90a5c9 |
When RewriteRule

|
Packit |
90a5c9 |
is used in VirtualHost or server context with
|
|
Packit |
90a5c9 |
version 2.2.22 or later of httpd, mod_rewrite
|
|
Packit |
90a5c9 |
will only process the rewrite rules if the request URI is a URL-path. This avoids
|
|
Packit |
90a5c9 |
some security issues where particular rules could allow
|
|
Packit |
90a5c9 |
"surprising" pattern expansions (see CVE-2011-3368
|
|
Packit |
90a5c9 |

|
|
Packit |
90a5c9 |
To lift the restriction on matching a URL-path, the
|
|
Packit |
90a5c9 |
AllowAnyURI option can be enabled, and
|
|
Packit |
90a5c9 |
mod_rewrite will apply the rule set to any
|
|
Packit |
90a5c9 |
request URI string, regardless of whether that string matches
|
|
Packit |
90a5c9 |
the URL-path grammar required by the HTTP specification.

Security Warning
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Enabling this option will make the server vulnerable to
|
|
Packit |
90a5c9 |
security issues if used with rewrite rules which are not
|
|
Packit |
90a5c9 |
carefully authored. It is strongly recommended
|
|
Packit |
90a5c9 |
that this option is not used. In particular, beware of input
|
|
Packit |
90a5c9 |
strings containing the '@' character which could
|
|
Packit |
90a5c9 |
change the interpretation of the transformed URI, as per the
|
|
Packit |
90a5c9 |
above CVE names.

Packit |
90a5c9 |

Packit |
90a5c9 |

|
|
Packit |
90a5c9 |
default behavior in 2.4.0 through 2.4.3, and the flag to restore it is

|
Packit |
90a5c9 |
When a relative substitution is made
|
|
Packit |
90a5c9 |
in directory (htaccess) context and RewriteBase has not been set, this module uses some
|
|
Packit |
90a5c9 |
extended URL and filesystem context information to change the
|
|
Packit |
90a5c9 |
relative substitution back into a URL. Modules such as
|
|
Packit |
90a5c9 |
mod_userdir and mod_alias
|
|
Packit |
90a5c9 |
supply this extended context info. Available in 2.4.16 and later.

90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Prior to 2.4.26, if a substitution was an absolute URL that matched
|
|
Packit |
90a5c9 |
the current virtual host, the URL might first be reduced to a URL-path
|
|
Packit |
90a5c9 |
and then later reduced to a local path. Since the URL can be reduced
|
|
Packit |
90a5c9 |
to a local path, the path should be prefixed with the document root.
|
|
Packit |
90a5c9 |
This prevents a file such as /tmp/myfile from being accessed when a
|
|
Packit |
90a5c9 |
request is made to http://host/file/myfile with the following
|
|
Packit |
90a5c9 |
RewriteRule.

|
Packit |
90a5c9 |
RewriteRule /file/(.*) http://localhost/tmp/$1
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
This option allows the old behavior to be used where the document
|
|
Packit |
90a5c9 |
root is not prefixed to a local path that was reduced from a
|
|
Packit |
90a5c9 |
URL. Available in 2.4.26 and later.

The RewriteRule directive is the real
|
|
Packit |
90a5c9 |
rewriting workhorse. The directive can occur more than once,
|
|
Packit |
90a5c9 |
with each instance defining a single rewrite rule. The
|
|
Packit |
90a5c9 |
order in which these rules are defined is important - this is the order
|
|
Packit |
90a5c9 |
in which they will be applied at run-time.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Pattern is
|
|
Packit |
90a5c9 |
a perl compatible regular
|
|
Packit |
90a5c9 |
expression. What this pattern is compared against varies depending
|
|
Packit |
90a5c9 |
on where the RewriteRule directive is defined.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
In VirtualHost context,
|
|
Packit |
90a5c9 |
The Pattern will initially be matched against the part of the
|
|
Packit |
90a5c9 |
URL after the hostname and port, and before the query string (e.g. "/app1/index.html").
|
|
Packit |
90a5c9 |
This is the (%-decoded) URL-path.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
In per-directory context (Directory and .htaccess),
|
|
Packit |
90a5c9 |
the Pattern is matched against only a partial path, for example a request
|
|
Packit |
90a5c9 |
of "/app1/index.html" may result in comparison against "app1/index.html"
|
|
Packit |
90a5c9 |
or "index.html" depending on where the RewriteRule is
|
|
Packit |
90a5c9 |
defined.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The directory path where the rule is defined is stripped from the currently mapped
|
|
Packit |
90a5c9 |
filesystem path before comparison (up to and including a trailing slash).
|
|
Packit |
90a5c9 |
The net result of this per-directory prefix stripping is that rules in
|
|
Packit |
90a5c9 |
this context only match against the portion of the currently mapped filesystem path
|
|
Packit |
90a5c9 |
"below" where the rule is defined.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Directives such as DocumentRoot and Alias, or even the
|
|
Packit |
90a5c9 |
result of previous RewriteRule substitutions, determine
|
|
Packit |
90a5c9 |
the currently mapped filesystem path.

|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
If you wish to match against the hostname, port, or query string, use a
|
|
Packit |
90a5c9 |
RewriteCond with the
|
|
Packit |
90a5c9 |
%{HTTP_HOST}, %{SERVER_PORT}, or
|
|
Packit |
90a5c9 |
%{QUERY_STRING} variables respectively.

Per-directory Rewrites
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The rewrite engine may be used in .htaccess files and in <Directory> sections, with some additional
|
|
Packit |
90a5c9 |
complexity.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
To enable the rewrite engine in this context, you need to set
|
|
Packit |
90a5c9 |
"RewriteEngine On" and
|
|
Packit |
90a5c9 |
"Options FollowSymLinks" must be enabled. If your
|
|
Packit |
90a5c9 |
administrator has disabled override of FollowSymLinks for
|
|
Packit |
90a5c9 |
a user's directory, then you cannot use the rewrite engine. This
|
|
Packit |
90a5c9 |
restriction is required for security reasons.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
See the RewriteBase
|
|
Packit |
90a5c9 |
directive for more information regarding what prefix will be added back to
|
|
Packit |
90a5c9 |
relative substitutions.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
If you wish to match against the full URL-path in a per-directory
|
|
Packit |
90a5c9 |
(htaccess) RewriteRule, use the %{REQUEST_URI} variable in
|
|
Packit |
90a5c9 |
a RewriteCond.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
The removed prefix always ends with a slash, meaning the matching occurs against a string which
|
|
Packit |
90a5c9 |
never has a leading slash. Therefore, a Pattern with ^/ never
|
|
Packit |
90a5c9 |
matches in per-directory context.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Although rewrite rules are syntactically permitted in <Location> and <Files> sections
|
|
Packit |
90a5c9 |
(including their regular expression counterparts), this
|
|
Packit |
90a5c9 |
should never be necessary and is unsupported. A likely feature
|
|
Packit |
90a5c9 |
to break in these contexts is relative substitutions.

Introduction.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
In mod_rewrite, the NOT character
|
|
Packit |
90a5c9 |
('!') is also available as a possible pattern
|
|
Packit |
90a5c9 |
prefix. This enables you to negate a pattern; to say, for instance:
|
|
Packit |
90a5c9 |
``if the current URL does NOT match this
|
|
Packit |
90a5c9 |
pattern''. This can be used for exceptional cases, where
|
|
Packit |
90a5c9 |
it is easier to match the negative pattern, or as a last
|
|
Packit |
90a5c9 |
default rule.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Note
|
|
Packit |
90a5c9 |
When using the NOT character to negate a pattern, you cannot include
|
|
Packit |
90a5c9 |
grouped wildcard parts in that pattern. This is because, when the
|
|
Packit |
90a5c9 |
pattern does NOT match (ie, the negation matches), there are no
|
|
Packit |
90a5c9 |
contents for the groups. Thus, if negated patterns are used, you
|
|
Packit |
90a5c9 |
cannot use $N in the substitution string!

90a5c9 |
The Substitution of a
|
|
Packit |
90a5c9 |
rewrite rule is the string that replaces the original URL-path that
|
|
Packit |
90a5c9 |
was matched by Pattern. The Substitution may
|
|
Packit |
90a5c9 |
be a:

file-system path
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Designates the location on the file-system of the resource
|
|
Packit |
90a5c9 |
to be delivered to the client. Substitutions are only
|
|
Packit |
90a5c9 |
treated as a file-system path when the rule is configured in
|
|
Packit |
90a5c9 |
server (virtualhost) context and the first component of the
|
|
Packit |
90a5c9 |
path in the substitution exists in the file-system
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
URL-path
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
A DocumentRoot-relative path to the
|
|
Packit |
90a5c9 |
resource to be served. Note that mod_rewrite
|
|
Packit |
90a5c9 |
tries to guess whether you have specified a file-system path
|
|
Packit |
90a5c9 |
or a URL-path by checking to see if the first segment of the
|
|
Packit |
90a5c9 |
path exists at the root of the file-system. For example, if
|
|
Packit |
90a5c9 |
you specify a Substitution string of
|
|
Packit |
90a5c9 |
/www/file.html, then this will be treated as a
|
|
Packit |
90a5c9 |
URL-path unless a directory named www
|
|
Packit |
90a5c9 |
exists at the root or your file-system (or, in the case of
|
|
Packit |
90a5c9 |
using rewrites in a .htaccess file, relative to
|
|
Packit |
90a5c9 |
your document root), in which case it will
|
|
Packit |
90a5c9 |
be treated as a file-system path. If you wish other
|
|
Packit |
90a5c9 |
URL-mapping directives (such as Alias) to be applied to the
|
|
Packit |
90a5c9 |
resulting URL-path, use the [PT] flag as
|
|
Packit |
90a5c9 |
described below.

Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Absolute URL
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
If an absolute URL is specified,
|
|
Packit |
90a5c9 |
mod_rewrite checks to see whether the
|
|
Packit |
90a5c9 |
hostname matches the current host. If it does, the scheme and
|
|
Packit |
90a5c9 |
hostname are stripped out and the resulting path is treated as
|
|
Packit |
90a5c9 |
a URL-path. Otherwise, an external redirect is performed for
|
|
Packit |
90a5c9 |
the given URL. To force an external redirect back to the
|
|
Packit |
90a5c9 |
current host, see the [R] flag below.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
- (dash)
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
A dash indicates that no substitution should be performed
|
|
Packit |
90a5c9 |
(the existing path is passed through untouched). This is used
|
|
Packit |
90a5c9 |
when a flag (see below) needs to be applied without changing
|
|
Packit |
90a5c9 |
the path.

Back-references are identifiers of the form
|
|
Packit |
90a5c9 |
$N
|
|
Packit |
90a5c9 |
(N=0..9), which will be replaced
|
|
Packit |
90a5c9 |
by the contents of the Nth group of the
|
|
Packit |
90a5c9 |
matched Pattern. The server-variables are the same
|
|
Packit |
90a5c9 |
as for the TestString of a
|
|
Packit |
90a5c9 |
RewriteCond
|
|
Packit |
90a5c9 |
directive. The mapping-functions come from the
|
|
Packit |
90a5c9 |
RewriteMap
|
|
Packit |
90a5c9 |
directive and are explained there.
|
|
Packit |
90a5c9 |
These three types of variables are expanded in the order above.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Rewrite rules are applied to the results of previous rewrite
|
|
Packit |
90a5c9 |
rules, in the order in which they are defined
|
|
Packit |
90a5c9 |
in the config file. The URL-path or file-system path (see "What is matched?", above) is completely
|
|
Packit |
90a5c9 |
replaced by the Substitution and the
|
|
Packit |
90a5c9 |
rewriting process continues until all rules have been applied,
|
|
Packit |
90a5c9 |
or it is explicitly terminated by an
|
|
Packit |
90a5c9 |
L flag,
|
|
Packit |
90a5c9 |
or other flag which implies immediate termination, such as
|
|
Packit |
90a5c9 |
END or
|
|
Packit |
90a5c9 |
F.

|
|
Packit |
90a5c9 |
Modifying the Query String
|
|
Packit |
90a5c9 |
By default, the query string is passed through unchanged. You
|
|
Packit |
90a5c9 |
can, however, create URLs in the substitution string containing
|
|
Packit |
90a5c9 |
a query string part. Simply use a question mark inside the
|
|
Packit |
90a5c9 |
substitution string to indicate that the following text should
|
|
Packit |
90a5c9 |
be re-injected into the query string. When you want to erase an
|
|
Packit |
90a5c9 |
existing query string, end the substitution string with just a
|
|
Packit |
90a5c9 |
question mark. To combine new and old query strings, use the
|
|
Packit |
90a5c9 |
[QSA] flag.
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
|
|
Packit |
90a5c9 |
Additionally you can set special actions to be performed by
|
|
Packit |
90a5c9 |
appending [flags]
|
|
Packit |
90a5c9 |
as the third argument to the RewriteRule
|
|
Packit |
90a5c9 |
directive. Flags is a comma-separated list, surround by square
|
|
Packit |
90a5c9 |
brackets, of any of the flags in the following table. More

Packit |
90a5c9 |
