Yes. Run the processes each on its own port (eg. 8000, 8001, 8002,
...) and then add all these ports as real servers.

I use this to do seamless upgrades of the application. I start the new
version up on an unused port, add it as real server, then set the
weight of the old version to zero and remove as real server once no
more clients are connected to it.

So that new clients won't connect to the old version. Existing
connections will continue to work, and once no client is connected to
the old version, it can be shut down. The scheduling method is
irrelevant, pick one which fits your setup best.

I think you can safely just remove the realserver, and still existing
connections will keep working until they terminate.

Setting weight to 0 still makes sense when you want to temporarily take
a realserver out of service, as the concurrent connection count for least-
connection scheduling is kept intact that way (and the connection count
can still be monitored while the weight is 0).
