Accessing Login page from CF

My dept is using one asp web app and one cf web app.

Both apps. kind of related, many people use both, sometimes at the same time.

To access these two apps, admin and users are using the same username and password.

I'm trying to build a login interface on the CF app. for users to login into the asp application, eliminating the need for users to open

another when they are already in the CF app.

So I use CF Hot Link technique (using cfhttp url="url for the asp login UI"> and I got the asp login screen show up on my CF web app.

How can I get this login "talk" to the action page on the asp side? is it even possible?

Thanks,

Alec
