 When using a proxy the browser send a full URL in var REQUEST_URI
 $_SERVER['REQUEST_URI'];

 i.e.:

 With proxy: it returns http://mydomain.com/requestedurl
 No Proxy: it returns /requestedurl

 Solution:
 check the variable to see if it is full path and transform it:

 {{{#!php
 <?php

 $_SERVER['REQUEST_URI'] = requesturl_format($_SERVER['HTTP_HOST'],
 $_SERVER['REQUEST_URI']);

     function requesturl_format($m_host, $m_request){
         $m_regex = sprintf('#(https?://)(%s)(/.*)#', $m_host);

         if(preg_match( $m_regex, $m_request, $matches)){
                 if(count($matches) == 4){

                         $m_host = ($matches[1]);
                         $m_domain = ($matches[2]);
                         $m_url_req = ($matches[3]);
                         return $m_url_req;
                 }
         }
         return $m_request;
     }
 }}}
