How much work for Windows Multiple Process support?

[itpp2012]

You can run multiple nginx sessions by seperating the config between
them, the main http section will have to use a 'uniqe' port for each
session, from there on you can seperate out the hosted websites and also
assign each session its own cpu. You are however limited to a 65.000
connection max for all sessions.

Another, easier, way for multiple sessions is to use 1 session as proxy
to many secondairy sessions which will make routing the http port
easier, this way also scales better.
