I...can't imagine how they could have. I guess if you got really ambitious and hacked up a Java filter to check for some parameter the IdP doesn't know about on the initial entry in, you could save it off somehow and then check for something later in your login.jsp.

Assuming we're talking about V2 here anyway.

There's a sort of hook for this in V3 but since SAML doesn't have that feature it isn't exercised at the moment.
