Hi,
I think the problem is that when you are doing your Post you can't use your
users session. You would actually be creating an entirely new session.
When you redirect to result.aspx you are back to using your users session.
I can't see a way of doing what you are trying to do from the server. With
my ecommerce sites I send my processor the amount of the purchase and a
description (usually an Invoice #). I also send the processor two URLs.
The processor then redirects to one URL upon success and to the other upon
failure. Once that redirection happens the user is back to using their own
session on my site.
All I can think of is after you do your post don't Response.Write the entire
message to the user. Find what you need in it and then just put that in a
label or textbox or cell or something. I post to other sites behind the
scenes all the time to grab information for my user but I don't send back
the entire contents of that response. For one thing it would mess up my
ASP.Net Form tag, for another the content type I get back from my post is
many times not the same content type my user requested my page with in their
browser. There is a very good chance that by doing what you are doing you
are messing up not only your Form tag but also possibly your view state and
if you are using cookieless sessions this could be why you are losing your
session state. I hope this helps. Good luck! Ken.
