If you check your web.config file in the webapp root youll find something like this:
Quote:<authentication mode="Forms">
<forms loginUrl="~/Account/Login" timeout="60" defaultUrl="~/admin"></forms>
</authentication>
loginUrl is the url of the forms authentication default loginpage. If you want to use your own just change the url and it should work.
Default url is where the user is sent after successful login if you use FormsAuthentication.RedirectFromLoginPage()
