A client of the BITS Peer-Caching: Peer Discovery Protocol uses the Probe message to solicit potential servers.

The format of the Probe message is as specified in [WS-Discovery] section 5.2. The following additional constraints are placed on the /s:Envelope/s:Body/d:Probe element:

  • A single d:Types child element MUST be present and include the type "msbits:PeerServer".

  • A single d:Scopes child element MUST be present and contain at least one scope.<23>

A client or server MUST support the "http://schemas.xmlsoap.org/ws/2005/04/discovery/rfc2396" matching rule and MAY support other rules.
