[erlang-questions] How to cluster mochiweb?

There isn't really any reason to cluster mochiweb (or any other HTTP
server). If you need to share session state amongst a couple machines
the web servers don't need to talk to each other, you just need a
distributed session store (e.g. mnesia).

When you do load balancing/failover the HTTP servers don't need to
talk to each other. Whatever is doing the load balancing normally does
its own polling to see which servers are alive and send requests to
only those.
