This is the nature of Forms Authentication. (which im guessing you're using).
That is, when you access a page which requires authentication, ASP.NET will redirect you to the login page, passing in the ReturnUrl as a parameter so you can be returned to the page you came from post-login.
To remove this functionality would break the semantics and design of Forms Authentication itself. (IMO)
My suggestion - if you dont need it, dont use it.
I'm trying to redirect the user to a
static page after login to do some
selections.
Piece of cake - after you've done your login, instead of doing FormsAuthentication.RedirectFromLoginPage (which uses that very ReturnUrl QueryString parameter), just use FormsAuthentication.SetAuthCookie and redirect wherever you want.
