As Chris said it is not that easy to determine which requests to route
by which proxy. Also, this routing has to be done at a low level in the
cache hierarchy (i.e. browsers), or you won't get much helped from it.

As I said earlier "half_closed_clients off" should get around the
problem induced at the TCP level. (if you have it off and still get a
problem with the number of pending TCP connections, then your proxy is
not dimensioned to handle the number of clients it has)

However, I see no way of getting around the problem that DNS queries
also get clogged down other than to run a exessive amount of dnsserver
processes just in case, even if only a few is used in normal operation.
Good news is that it won't hurt you much to do so (a few KB of memory,
and one filedescriptor to each dnsserver).
