Subject questions regarding the keep alive mechanism
Date Fri, 01 May 2009 06:05:07 GMT

Hello all,

I am trying to understand how the keep alive is implemented in two versions
of ActiveMQ (4.1.1 and 5.2.0). 

1) Is it the case (in version 4.1.0) that both the client and the broker are
sending the KeepAliveInfo command or this is only sent by the client? In
version 4.1.0: is it true that the broker does not acknowledge the keep
alive sent by clients?

2) Is it true that the exact same code (the InactivityMonitor class) is
running on both the server and the client (question valid for both

3) Was the way that the keep alive is implemented changed between version
4.1.0 and version 5.2.0 (in terms of this biderectional pinging)?
