Sure, we do too with mirrormanager. For long-lived requests, it makes
all sorts of sense. For very short-lived requests, where the
connection setup/teardown time dominates, less interesting.
Its worth noting that perhaps its time to look at alternative proxy
frontend. Last time I looked there were either good balancers, or good
cachers, but not the both. But its quite possible we've outgrown our
simple apache setup.
