Ajax unauthorized display status: 0 instead of 401


Description of the issue:
When performing an ajax request whilst unauthorized on a website the status is returned as ‘0’ (failed) instead of ‘401’. I have testing this on Firefox, Internet Explorer and Chrome which all return ‘401’ (unauthorized).

The authentication method is forms authentication on a C# web forms application, framework 4.5.1.

Steps to Reproduce (add as many as necessary):

  1. Create a simple test ajax method which is contained on a forms authenticated page.
  2. Login to the website and navigate to the page containing the ajax test method.
  3. Remove the authentication cookie or clear the browser history to remove the authentication.
  4. Run the ajax method and look at the returned status code.
