Support ajax clients in multiple windows/tabs in a single browser
-----------------------------------------------------------------
Key: AMQ-2948
URL: https://issues.apache.org/activemq/browse/AMQ-2948
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.4.1
Environment: OSX 10.6
Centos 5.4
Reporter: Alex Dean
Attachments: support-multiple-ajax-clients-per-session.patch
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.
