Remote Desktop Web Connection diagram wanted

[Rich Raffenetti]

I am looking for a remote desktop web connection diagram that would show the
communication/protocol/port# flow. I am particularly interested in the
details of encryption on each leg of the communication.

The ideal diagram would show the web client, the web server, and the server
(X) to which a connection is made from the web client.

The Microsoft overview describes encryption between the browser and X. Is
that encryption independent of SSL on the web site?

I would assume that SSL only protects the browser/web server traffic on port
80.

Evidently the web server passes the port 3389 traffic through from the
browser and X. Is that right?

Does anyone know of a technical reference with a good diagram? Thanks.

There's no encryption at all involved until the ActiveX control at the
client end uses RDP (over port 3389, TCP) to contact Remote Desktop on the
host end.

That connection is encrypted from the start--i.e. before the logon dialog is
displayed.

Before that point, i.e. before RDP is involved, there's no encryption at
all. SSL isn't involved anywhere, although there's no reason why it
couldn't be, as far as I know.
