Kumar, This seems to be more of a non-lucene problem. Anyhow, have a look at "ha-proxy"; this is closer to what you require.
We can discuss more on this off the lucene list, if required.

Hi Kapil, Thanks for your response. We are looking at replicating complete lucene index on both servers. The main reason for this is the ease of scaling compared to say splitting the index between the 2 servers. Since we will have separate indexes we won't be using MultiSearcher/ParallelMultiSearcher. We are using domain based cookie as opposed to server based cookie. But we are using HTTPSession for storing the more complicated datastructures as it allows easier manipulation of objects. The problem we for us is sharing this information between two tomcat servers running lucene searches. And we plan on using both servers for rendering results directly to the end user. We are not sure about the load balancer yet. That is what we are trying to find out. I was thinking of using LVS, but not sure how easy is it to use. I also found the Persistence feature to be quite useful. Is there any better solution for load balancing? Chhabra, Kapil wrote: > > Ah!
