How reverse proxy knows to balance between couple of twistd processes? Do you have may be an example(or doc link) of such proxy that can distributing connections to each twistd process?
This is a classic distributed systems architecture. A reverse proxy can either something like haproxy, nginx, apache, perlbal or whatever (even another twisted process). The twistd processes can be seen as simply other machines on a LAN - instead they all have the 127.0.0.1:<port> where the port is different for each process. I don't have a more comprehensive example, but there are many many examples of reverse proxying servers all over the place - google "nginx reverse proxy" for many examples. Hope that helps.
