Like Kevin said, the granularity of information the IdP has about the
SP is the the SP as a whole, i.e. its entityID.  So if you need
differing behaviour at the IdP (any, really) for several resources at
the SP, you'll need to make those resources seperate logical SPs, with
their own entityIDs and SAML metadata.
