I don't believe so.  I'd say that the diagram accurately refers to it as
an HTTP proxy.

I'm pretty sure that a HTTP gateway cannot be a SOAP intermediary,
because SOAP and HTTP are at the same layer in the protocol stack, and
therefore share an addressing model (when bound).

Ok.  Do you want to propose an edit that would make that clearer?
