sessionId generation, uniqueness, customizing sessionId
1) How does glassfish generate sessionIds?
2) Are glassfish sessionIds unique to the machine and process? (e.g. assume X glassfish instances on X servers NOT running in a cluster, but each operating independently, are the sessionIds generated by each instance guaranteed to be unique?)
If the answer to #2 is no, is there a way to specify a custom sessionId generator? I found something (here: http://wiki.glassfish.java.net/Wiki.jsp?page=SupportWLDDInContainers) saying "GlassFish does not provide configuration support for session id length, but supports custom session id generation algorithms via the "sessionIdGeneratorClassname" session manager property".
However, I have had not been able to find much else online regarding the "sessionIdGeneratorClassname" session manager property. Any info about this? It's not mentioned in the GFv3 developer guide.
