Thanks Alex,
I see, so if app0, app1 and app2 are on different machines and say the
first request from the client hits app0, and app0 forks a process to handle
the session with the client. I presume that the subsequent requests from
the client would somehow be routed to app0 - correct? if so,

Hi Alex,
This is the definition of loadbalancing from
https://www.nginx.com/resources/glossary/load-balancing/ nginx is a
popularly used as a loadbalancer - while this is an L7(application layer
from OSI) load balancer, the term loadbalancer can be used for other layers
too.

I would say it is a general rule, following from the (CAR . CDR) principle of
Lisp data.
In our case, the CAR is 'cond' and

As I said, I don't know about load balancers. But in any case it depends on the
structure of the system. Is it a static system, which can be put on several

The 'prog' is ugly. We should better avoid it. As logging
does its own 'out', we can move

Usually I log only new sessions, by loading @lib/app.l in production
applications. This logs with 'msg' calls at the end of
