Saravanan Thoppan commented on AMQ-2948:
----------------------------------------

Slight change in my words - However, when U1 logs out of the application and logs in back
for bidding and when he starts bidding, the update doesnt come to his winidow but the other
users U2 sees the price information being updated on his.

> Centos 5.4

> In current ajax code, there is a 1-1 relationship between ajax client and session.  Since
multiple windows in the same browser share the same session, it's impossible for the ajax
code to update both windows.  Either 1 or the other will receive messages, but not both.
> The attached patch allows an optional 'clientId' string to be passed to the JavaScript
amq.init() function, similar to that supported by the REST servlet.  This clientId string
is sent to the server with every ajax request.  In MessageListenerServlet, a new consumer
is created for every new sessionid+clientId, allowing multiple windows in the same browser
to send & receive messages independently.
> For some (currently) unknown reason, IE7 cannot send messages from multiple windows.
 2 IE7 windows can receive messages independently with no errors, but once either IE7 window
sends a message, both windows cease receiving data.  This behavior is not seen in FF (OSX
or WinXP) or Safari (OSX).  All those browsers are able to send & receive simultaneously
in multiple windows with no errors.
