  +    <p>An internal redirect happens, for example, when using the <directive
  +    module="mod_actions">Action</directive> directive, which internally
  +    redirects the original request to a CGI script. A subrequest is Apache's
  +    mechanism to find out what would happen for some URI if it were requested.
  +    For example, <module>mod_dir</module> uses subrequests to look for the
  +    files listed in the <directive module="mod_dir">DirectoryIndex</directive>
  +    directive.</p>
  +    <p><directive>LimitInternalRecursion</directive> prevents the server
  +    from crashing when entering an infinite loop of internal redirects or
  +    subrequests. Such loops are usually caused by misconfigurations.</p>
  +    <p>The directive stores two different limits, which are evaluated on
  +    per-request basis. The first <var>number</var> is the maximum number of
  +    internal redirects, that may follow each other. The second <var>number</var>
  +    determines, how deep subrequests may be nested. If you specify only one
  +    <var>number</var>, it will be assigned to both limits.</p>
