a) SAML provides for relay state information to be passed
in the authnrequest and returned in the Response.
b) The SP can store it's own information in the browser
(via cookie) prior to sending the user to the IdP and use this information when
the IdP sends the browser back.

[saml-dev] SSO Browser profile question
Hello *,
Which mechanisms does SAML provide for maintaining the state
between the initial resource request of the User Agent and the actual response
of the SP? (SSO Browser profile). I will clarify my question with a small example:
A User Agent accesses a resource on an SP for which it has
no security context:
UA requests a resource on the SP.
SP responds with an <AuthnRequest>. (-> no
security context)
<AuthnRequest>gets redirected to the IdP.
IdP redirects an assertion about the Principal to the
SP.
SP responds to UA. (-> requested
resource)
Which SAML mechanisms can be used by an SP to correlate the
initial resource request (step 1) with the redirected assertion (step 4)? In
other words, how does the SP know which resource it has to provide based on
the response of the IdP?
Best
regards,
Jurgen
