  <title>代理服务器设置</title>

<section id="what">
  <title>什么是代理？</title>

  <p>A <em>web proxy</em> filters websites that you look at, it receives
  requests from your web browser to fetch web pages and their elements, and
  following a policy will decide to pass them you back. They are commonly used
  in businesses and at public wireless hotspots to control what websites you
  can look at, prevent you from accessing the internet without logging in, or
  to do security checks on websites.</p>
