Redirect or switch from https to http

Hello,

I'm trying to authenticate users through https (SSL), but after the user get authenticated I want to revert back to http (non-SSL) to redirect users to some .aspx page. I'm able to redirect users but protocol doesn't change in the browser from https (for login.aspx) to http after authentication.

I've IIS 7 web server.

Let me know your ideas how to switch from https to http after user authentication.

Cheers
