title: Empty HTTP response headers and body
body: <p>I am able to consistently reproduce this problem where I request a URL from my server and I get back a 200 code but the response headers and response body are empty.  If I monitor incoming traffic on my web server I never see the request come in.  My web server sits behind a proxy server, if I monitor traffic there, I also do not see the request come in.</p>
  
  <p>Any ideas as to where this empty response might be coming from, or tips as to what situations can result in an empty response like this?</p>
