This will work in the way you ask if your application destroyed
the cosign service cookie it was using before sending the user
on to the weblogin server logout page.  When the user clicks
"back", mod_cosign on your server will see that while the user
is authenticated, that they do not have a service cookie for
the server and after doing the cosign REGISTER will then send
them off to the CosignSiteEntry.

I like Paul's solution, too, though.
