My default.aspx, which allows all users, has a login button.
I want to have an authenticated user redirected to another specific page, for instance main.aspx, after logging in through the login button (page)

How to do that?

I tried using the FormsAuthentication.RedirectFromLoginPage but I have no control of the page it redirects to

Thanks

You can either use Server.Transfer or Response.Redirect.

Server.Transfer("PageToRedirectTo.aspx")

or

Response.Redirect("PageToRedirectTo.aspx")

J

"RedirectFromLoginPage" is used for automatically returning you to the page you attempted to access when the application detects that you are not logged in. When the application redirects you to the login page, it tells the login page what page you were trying to get to so it can send you back. Very useful, but not for what you want to do.

You need to use Response.Redirect("main.aspx")

IMPORTANT: You still need to save the login cookie! When you use "RedirectFromLoginPage", ASP.NET writes the authentication cookie AND issues the Response.Redirect for you. If you want to redirect to a specific page, you'll need to first set the login cookie with the FormsAuthentication.SetAuthCookie method then issue your specific redirect.

Thanks planoie - a very accurate answer
