I would still promote the usage of Network between the web server and core
daemon. This keeps open the possibility of spawning multiple daemon
processes with a single web server. We could apply load balancing between
the daemons in some consistent fashion.
At the same time, I would like to keep the operations performed by the web
server to be minimal. I imagine the server daemon to do all the job. The web
server (in my opinion) is just a middleman in passing on requests and
responses in HTTPS. Anyone have thoughts on anything in particular (that is
load intensive) that the web server needs to handle?
