Weird login problem on asp.net web application in IE

Question

In my web application when i try to login in from Mozilla or chrome, it takes me to the correct url that im redirecting to after authentication, im using form-authentication.

But when i try to do that in IE, it just puts my intended URL in the query string as return and gives me the login prompt again.

Does any one have any ideas as to why this might be and how can it be fixed.

To Redirect im using

FormsAuthentication.SetAuthCookie(username, false);
                    Response.Redirect(redirectUrl);

This login was working even in IE before i put code to allow for access from an external application, which involves creation of new aspnet user if required. Can this be the problem.

Answer 1

Your should to use FormsAuthentication.RedirectFromLoginPage method.
