title: How do I set up a Web Proxy that I can use to test functionality related to Http Requests?
body: <p>one of the users of my applications must connect to a web proxy before he can connect to our website. he tells me that he keeps getting 401 errors even when he specifies the proxy's ip, port, username &amp; password. I have no way to test this functionality because I don't need to use a proxy to connect to our website. For all I know the problem relates to the way I am making the HttpRequest, but again, I have no way to test this functionality.</p>
  
  <p>How can I set up a web proxy that will allow me to test this functionality?</p>
