I agree with Kevin (as usual.)
A shared backend database is the way this kind of thing is normally done.

Cookie.

The Forms Authentication cookie if you're using Forms Authentication. In
that case, make sure both applications have the same machineKey settings in
web.config and make sure they are in the same domain (e.g., the domain of
the cookie is "surfcontrol.com" and the sites are "a.surfcontrol.com" and
"b.surfcontrol.com").

Hi.

I have an web app that handles the login, user access etc. I want this login
to redirect to an other web app and give that web app the userid etc.
without sending it to the client... How?
