I have web application that has Windows authentication running successfully until recently. I didn't do any changes to IIS configuration or code modification or user permissions change.
I can log in to the application, but when javascript does redirect it returns to the same page. I checked with fiddler headers. Once I initially logged-in the header has WWW-Authenticate parameter. When the redirection done through JavaScript code either AJAX or setting windows.lovation.href='MyPage' it does not pass WWW-Authenticate header value.
So, once I go directly to any page under this application it loads fine and I see WWW-Authenticate parameter, but with JavaScript the WWW-Authenticate parameter missing. Once again no change was done to server.
I assume it may relate to windows auto updates. But it is just wild guess.
