Using YafMembershipProvider & YafRoleProvider to pass a logged in user from the parent website to the YAF forum subdirectory (https://www.parent.com/forum).

I'm testing, and YafMembershipProvider & YafRoleProvider seem to be processing the user fine.

When I jump into the forums with Response.Redirect("/forum" ); I get to the opening page, but it shows me as not being logged in.

If I redirect with Response.Redirect("/forum/default.aspx" ) I AM logged in, but can't seem to go anywhere.

https://www.parent.com:443/Forum/cp_profile 

There isn't a /cp_profile folder under /forum. So there must be some pages that YAF is building on the fly? What do I need to do to get them to function?

I believe that web.config and app.config are as recommended, but could that be the issue somewhere?

What is the basic coding technique being used here so I can get some background on how it works.
