Martin, Why would the session be lost? The second haproxy instance would recognise the cookies and send to the correct server in the application pool.
Unless you mean the actual TCP session? I'm pretty sure even F5 doesn't support TCP session fail over, and the replication of tcp sessions would swamp the network. Or have I got the wrong end of the stick as usual? 2009/3/3 Martin Karbon <martin.kar...@asbz.it> > > Hi! > just wanted to know if anyone knows an opensource solution for a so called > transparent failover: what I mean with that is, I installed two machines with > haproxy on it which comunicate with each other via heartbeat.
