I have done some experiments. You will need:Depends mainly on the load-balancer but I don't see any issue as long as you can have "sticky" sessions.
- sticky sessions (i.e. all sessions go to the same server)
- Well replicated content
- Well replicated psml resources (either files or use DBPSML)
- A common or replicated DB to handle USER information (and possibly PSML).
The issue of replicating PSML (or having DBPSML) arises from the ability of a session to write a customized PSML, logout, and then get a new session in a different server.
External resources (such as the ones that the URL cache handles) will be fetched repeatedly unless you fix it either by having a external proxy or you rewrite the URL cache as a remote one.
Using a proxy will not work completely, as most or the external feeds are marked by their origin servers as "non-cacheable".

Objet : Jetspeed on the farm -yee-ha
Will jetspeed work on a multi server farm behind a load balancer ?
Has anyone tried it, if it should work?
thanks,
