+ <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>
