In all my deployments of tomcat I have never seen the point of a custom 
protocol that did exactly what HTTP does, so all my tomcat deployments 
are all HTTP, with a simple mod_proxy frontend.

Even the "get Apache to server static content" feature wasn't enough of 
a drawcard, as proper HTTP cache handling and a suitable cache solved 
this problem. It was far more important for me to arrange the web 
application as a self contained unit - I would rather be more tidy with 
an install at the expense of a slightly higher load, than sacrifice a 
clean install to save some cycles.

Proxy has a placeholder in it that says "put the code to make decision 
about load balancing etc here" - all that is needed is a hook and a 
module "proxy_loadbalancing.c" to make it happen.

This is possibly a whole separate project in itself.

I have been meaning to work on a get-apache-config-out-of-ldap extension 
for a while, what it really should be is "get apache config out of 
wherever", but this should be an Apache wide thing, not limited to a 
single module or technology.
