title: .NET and IIS timeout for individual AJAX request
body: <p>I have an application written with a basic HTML/CSS/Javascript front end, and sending AJAX requests using EXTJS to .NET ASHX handlers.  One particular request can take a long time to execute, and it appears to be getting cut off at exactly 30 seconds.  How do I go about adjusting this timeout value?</p>
  
  <p>Here is what I've tried/discovered.</p>
  
  <ol>
  <li>It functions the same in multiple browsers (Chrome, IE, Firefox), so
  I assume it is a configuration on the server side. </li>
  <li>I've looked through the IIS configuration and found a timeout that appears to be
  for session timeouts and it's set to 120 (minutes I presume). </li>
  <li>The request works fine when a smaller data set is requested, so there
  are no other known programming bugs causing this specific issue.</li>
  </ol>
