   2  * Originally this was supposed to intercept http calls and redirect them
   3  * but that is not supported in webkit2 (without using the extension api)
   4  *
   5  * so for now we have modified our server to serve use a base url of xhttp:
   6  *
   7  * so all relative urls are based on that
   8  *
   9  * Idea is to serve the files from the file system, so no need to setup apache etc...
  10  * This should work for the static content like css / javascript etc.. but
  11  * will cause issues with 'dynamic' xhr files (eg. the php stuff)
  12  *
  13  * the idea is nicked from geary.
