You can do it any way you like. I have systems that are setup using
Perlbal and/or nginx ( which I will call proxy ) in the following
situations:
1) proxy on 80 to apache1/mp1 on localhost:8000
2) proxy on 80 and 443 to apache1/mp1 on localhost:8000 and
apache2/mp2/perl 5.8 on localhost:8001
3) proxy on 80 and 443 to several different apache2/mp2 servers on a
local network.
On one system I even have several "instances" of Apache running on
localhost on various ports basically one instance per mod_perl
"application" due to the traffic patterns/memory usage of the
applications. Since one app is a HUGE memory hog and very light on
traffic it is setup with just two Apache child processes and the other
apps are setup with more children.
Hope this helps.
