Link between one SAML request and its SAML response

[eTouchard]

Hi

I would like to link an SAML request to its response. After reading some stuff on internet it seems that the relayState is ment to be used.
Is it the same as defined in redirectToIdentityProvider method ?
And by the way do you know how to get it form an SamlResponse ?

Regards
Eric (again)

RelayState and SamlResponse will both be servlet parameters of the HTTP request, so you can do something like this:

String relayState = request.getParameter("RelayState");
SamlResponse samlResponse = client.processPostFromIdentityProvider(request);

You can then add them to a map or link them however you like.
