    Re: Forms Authentication help please!

    Hello,

    Have you stepped through the code in the debugger? Does it take the path that you would expect?

    Have you tried taking off the URL rewriting, to see if it works?

    Don't try to do too many things at once. Break things into smaller chunks, and make sure that they are working in isolation, before trying it as a whole.

    Re: Forms Authentication help please!

    Apparently the issue I am running into is due to me rewriting the url. Any ideas on correcting this issue?

    Thanks!

    Off the top of my head, unfortunately not. URL Rewriting is not something that I have really played with.
