title: diagnose 404 for asp net POST request
body: <p>How can i diagnose the 404 errors on my asp.net application.
  It seems in iis logs that GET request to my *.aspx page return success ( code 200)
  The POST request to same page returns a 404 error , not able to diagnose why.</p>
  
  <p>Is there a seperate setting to allow POST request to this page or some where in the application.</p>
  
  <p><strong>Edit #1</strong>
  The Page has a grid ( ingragistics grid, third party control) that makes a xmlhttprequest to the page itself to load some data on the fly. It sometimes work but mostly give a 404.</p>
  
  <p>fidler also confrims the 404 error with the url &amp; that url does exist and is correct. </p>
  
  <p>I also verified the logs in IIS it confirm the 404 error. But not able to detect where the issue is.</p>
