S?SY?YN?NO?OP?PS?SI?IS?S

       If you want people to actually see the results of your network

       monitoring efforts you will need a webserver.

       This document lists some configuration hints for webservers.

       Contributions welcome.

       A big issue with mrtg monitoring data is the expiry time.  All these

       nice graphs you can create are only valid for a short time.  If you do

       not take special action some webbrowsers will not notice this and you

       may end up with people seeing old data because of caching issues.

       The apache module mod_expire allows you to setup special expiry

       properties for individual file.

       Here is an example for how this may look for an mrtg web directory.

       The configuration directives can be stored into a _?._?h_?t_?a_?c_?c_?e_?s_?s file.

        # Example .htaccess for use with apache-1.2 and mod_expire.

        # (mod_expire come with apache-1.2 but you have to explicitly

        # activate it when compiling the httpd ...)
