Hi Fernando
We could use Server.Transfer which would solve the problem (apart from the
Forms redirect issue) but what I'd like to know is is this a bug, or is it
working as it should?
I need to know as changing all of our Response.Redirects is obviously going
to cost a lot of money!
Many Thanks
Andy
