Weblogic JSessionId uniqueness
I have two linked questions about the uniqueness of the JSsssionId, I'm interested especially on the sessionId part (i.e. before node identifiers and timestamp):
1) How is the unique generation of sessionIds guaranteed in a cluster of weblogic Servers ? (if it is, I imagine statistically).
2) Which algorith is used to compute it? In case of a pseudo random algorithm it would be interesting to have an idea about the probability of having clashes.
Thanks.
