Subject Re: [PATCH] Goofing with proxy load balancing

Is it possible to call this hook something more general than "load 
balancing", as load balancing is just one possible function of this.

Also, something that would be really useful is for a "load 
balancer/backhand" module is the ability for the module hook to return 

Say for example a stateful module that watches JSESSIONID and passes all 
common requests to the same backend server, might choose to decline to 
perform, based on the cookie being missing, etc. Then, the next module 
in line (eg simple-round-robin) gets a go.

There would have to be a second hook in there, after the request is 
complete, so that the stateful module could see JSESSIONID when it was 
set the first time.
