I was thinking of doing something like this for quite some time.
the only issues I can see are
keepalives..
* do they handle things like cookies per request or per
connection?
* authentication
* handling of keepalive timeouts might be tricky
* ie.. do keepalives keep some state, I am never sure
there are also some other minor problems if you want to load balance the
backendservers, as that would break.
The reason I never pursued it was due to the backends we use being so
pathetic that they can't even handle simple Keep-alives without falling
over.
Oh apr_reslist would be a good starting point for this.
