title: Servlet unavailable in AppEngine with Android Client
body: <p>I am getting the following info log in GAE's console:
  "POST /xxx HTTP/1.1" 200 133 - "Apache-HttpClient/UNAVAILABLE (java 1.4),gzip(gfe)"</p>
  
  <p>I can not understand if the servlet is not available, why is "200" being returned. I checked web.xml file for servlet mapping and they seem fine. What else could be causing it. Is it even an error on GAE or is it due to client error.</p>
