Problem conclusion

When the SAML Web SSO TAI, ACSTrustAssociationInterceptor, is
invoked for an unauthenticated request, it sets a cookie
called WasSamlSpReqUrl to store the original request URL from
the client before it redirects them to the error page (usually
the IdP login page).  If the client neglects to login, and
instead requests another resource protected by the TAI, the
cookie value does not change.

The SAML Web SSO runtime is updated to always set the
WasSamlSpReqUrl cookie value to the URL of the latest request.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.37, 8.0.0.10, 8.5.5.4.  Please refer to the
