Inline Framse and SSL

Anybody got any ideas for this scenario:

A form is being filled out. The form is located inside of a scrollable
inline frame. When it comes time to enter secure information, the user
is transported to a new browser window, this new window is secure
using the server SSL certificate. The user completes the secure part,
the transaction is complete and the user closes the window(because
there is no navigation items in the new browser).

What the user sees after closing the secure window is the form page
prior to the launch of the new window. This might be confusing and
some people may actually complete the process again.

Is it possible to have a "double link". I mean, when the user is
transported to the new browser window, the inline frame will also load
another page of my choice with some type of message.

Thanks,

-Ray
