I am using Forms Authentication with ASP.NET 1.1. In the page_load method of my login class, the code does an automatic authentication by active directory and if successful, redirects to the originally requested page by FormsAuthentication.RedirectFromLoginPage(...). However, sometimes the redirection works and everything is fine but sometimes, after the redirect and end of page_load(), the browser displays an "Action canceled" error like below.
The try catch block in page_load method does not catch any exception at all. The error does not seem to be affected by timeout. And it seems to be server error.
Does anyone have any idea what might be wrong?
Thanks.
