How are Outlook Anywhere clients Proxied from Client Access Server to Mailbox (in same site)?

Where is the official Microsoft documentation on this?

I have read: https://technet.microsoft.com/en-us/library/bb310763(v=exchg.141).aspx

but this seems to only cover OWA, ActiveSync, IMAP & POP.  It does mention that clients (probably Outlook) use the CAS server (role) to obtain availability and autodiscover information... BUT ... is that all?

Thank you.

RPC over HTTP is used by OWA and Outlook Anywhere.

Would you agree that OWA encapsulates at the server and Outlook Anywhere is sending RPC calls encapsulated by HTTP directly from the client.
I am speaking of the client traffic to the server.

oh wait this question is asking about how Outlook (making a request of a CAS server) is proxied to its Mailbox.  More specifically, when the CAS server lives in a subnet that is the SAME as the mailbox server.

Is it CAS to CAS proxying or a direct connection from CAS to MBX server?  Any supporting documentation?
Entourage 2008 web services edition was first to use this protocol - i.e browsing OWA site under the hood.
