Is it possible to share session between two web applications deployed on different weblogic domains - with Coherence*Web in place?
I found that it's possible to share sessions state between different domains (i.e. each domain having a coherence cluster) with Coherence Federation. If you are using WebLogic, go to Environment > Coherence Clusters > <Your cluster> > Federation and add a remote participant. If multiple remote participants are there, you can provide a tangosol-coherence-override.xml with an appropriate topology / participants.
