1.4 Relationship to Other Protocols
This protocol and the Autodiscover HTTP Service Protocol described in [MS-OXDISCO] work together to use the standard HTTP mechanisms described in [RFC2068] to provide client management over the Internet. This protocol requires the Autodiscover HTTP Service Protocol to find Autodiscover servers that support this protocol. A higher-level protocol, given a server name or URL, uses this protocol to locate the corresponding fully qualified domain name (FQDN).
For conceptual background information and overviews of the relationships and interactions between this and other protocols, see [MS-OXPROTO].
