You are starting to convince me.  : ) 

Now there is some static content that I want to control access to -- but 
I presume that I can do that in the Apache2 front end, passing those 
requests to Apache1.3?

The 15:1 connection:Apache1.3 process ratio is certainly very 
attractive.  How many threads per process are you running on the Apache2 
front end?

I'll do some reading, but sample reverse proxy httpd.conf would be much 
appreciated -- thanks.
