What I have been running lately is an Apache2.2 with the worker MPM as a  proxy, and a 
good-old Apache1.3 with mod_perl+Apache::ASP as the "real" server. The mod_perl 
server serves the dynamic ASP pages, while the front servert the static content. This is 
a very typical configuration IMHO.

I could once (something like two years ago?) make Apache::ASP run with Apache 2.0, but that was a long time ago... since then, I stick to the above config - which I recommend to you if you do not want to waste too much time on figuring out all the stuff about Apache2.x and mod_perl (even though it shouldn't be too hard). 

For the record: we do somewhere around 6M-8M pageviews per month (see 
http://www.kepeslap.com at http://www.apache-asp.org/sites.html), which peeks 
to approx. 500-700k pageviews per day in busy periods. This is a 1.8Ghz Core2 
with 3G RAM, in a shared environment (with two other rather busy sites running 
on the same server). CPU utilization reaches 50% of all available CPU time, 
tops (I guess half of that is coming from the ASP site).


Hope this helps.
