Server.Transfer... won't transfer

Hi,
I have a login usercontrol which redirects to a specific login if invalid credentials are input. The user control sits in the header bar of each page and provides quick access.
I currently use response.redirect to do this but want to use context.items as I have some information I would like to pass as well.
On the page I have this:
            Server.Transfer("login.aspx");
            //Response.Redirect("login.aspx", true);
The problem is that the page does not transfer anywhere - it just site there... no messages no nothing!
I'm more than a little confused.  Am I useing server.transfer correctly?
Help!!!
 
John
