- add note here in light of CVE-2011-3368

    <p>If you require a more flexible reverse-proxy configuration, see the

    <directive module="mod_rewrite">RewriteRule</directive> directive with the

    <code>[P]</code> flag.</p>

    <note type="warning">

      <title>Security Warning</title>

      <p>Take care when constructing the target URL of the rule, considering

        the security impact from allowing the client influence over the set of

        URLs to which your server will act as a proxy.  Ensure that the scheme

        and hostname part of the URL is either fixed, or does not allow the

        client undue influence.</p>
