Subject Re: multiple ajax clients in the same browser?

Hi Alex,

with REST API (which shares some common code with Ajax stuff), you can
send clientId parameter to create/use client with the specified id
(and not be tied to the session). IMHO it should work the same with
Ajax API, so you can try with that for starters. If it doesn't work,
take a look at MessageListenerServlet

as that is where's the most of the server side logic is implemented.

If you need to look at the REST Servlet for the reference, take a look at
