Why? Why would we care which backend a request goes to, in
general. And, do we not want to use keepalives as much as possible
to the backends?
Let's assume that you have Apache setup as a proxy and furthermore
it's configured so that /html goes to foo1 and /images goes
to /foo2.
A request comes in for /html/index.htm, and gets proxied to
foo1, as it should; the connection is kept-alive, and a
request for /images/blarf.gif is requested; this should not
be sent to the just kept-alive server, but instead to
foo2...
So we need to ensure that this doesn't happen. We had a similar
type bug when picking workers out, which was patched in
349723...
