1.4 Relationship to Other Protocols

The Web Distributed Authoring and Versioning (WebDAV) Extensions for Calendar Support depend on the HTTP Extensions for Distributed Authoring -- WebDAV, as described in [RFC2518]. WebDAV, in turn, relies on Hypertext Transfer Protocol (HTTP) 1.1, as described in [RFC2068]. These extensions also rely on the Hypertext Transfer Protocol over Secure Sockets Layer (HTTPS), as specified in [RFC2818], for data protection services.

The WebDAV Extensions for Calendaring Support are also dependent on the client, server, and Microsoft extensions to [RFC2518] as described in [MS-WDV], [MS-WDVSE], and [MS-WDVME].

This specification is similar in scope to [RFC4791]; however, the requirements for this specification were created before [RFC4791]. While similar in concept, the WebDAV Extensions for Calendaring Support are not fully compatible with the Calendaring Extensions to WebDAV described in [RFC4791].

For conceptual background information and overviews of the relationships and interactions between this and other protocols, see [MS-OXPROTO].
