Hm, maybe I understand the question better now. Let me rephrase it into
what
I think you might have meant:
2) When another client sends a Message to my client via the server, is
there
any way to tell which client the Message originated from?
The answer is yes, if the sending client added a string field to his
Message
with the field name PR_NAME_SESSION. It doesn't matter what string he
adds,
because the server checks for this special field name and if it exists,
the
server will automatically replace its string-value with the session ID
of the
sending client. (This was added to prevent people from "spoofing"
messages
from other clients ... someone on BeShare had figured out how to hack
their
client so that they could put words into other peoples' mouths, which
was a
great way to cause chaos :^))
So if you get a message from the server that has a PR_NAME_SESSION
string
field in it, you can be sure that the message is from the client
specified in
that field. If the message doesn't have a PR_NAME_SESSION string field
(because the sender didn't add one), then there is no guaranteed way to
know
where it came from.
