title: IIS7.5 400 Bad request when a URL includes character :
body: <p>I am using ARR and ISAPI with IIS7.5.
  Whenever forwarding URL including specific character :
  400 Bad request occurs.
  How can I solve it?</p>
  
  <p>I guess there is no problem in ARR and ISAPI because no problem in development server(same Env as operating server) it only occurs in operating server.</p>
