1.7 Versioning and Capability Negotiation

  • Article

The Web Browser Federated Sign-On Protocol as described in [MS-MWBF] section 1.7 defers all versioning and capability negotiation to [WSFederation], [WSFederation1.2], and [RFC2616].

When using the Query String Response Transfer Protocol, an IP/STS uses the presence of the ttpindex parameter (as specified in section 2.2.2.1.1) in the request to determine whether the Query String Response Transfer Protocol is used for the response.

The SAML 1.1 Assertion Extension uses SIDs. SIDs have a revision mechanism. For more information, see [MS-DTYP], as specified in section 2.1.
