Our main problem with varnish is that when some backend or even a remote
server is very slow, keepalive towards the clients are queueing up
thousands of request just idling, waiting for some other object to be
finished.
Setting down keep-alive might help in this situation.
When varnish ends up in a thread-pile, even removing the original cause
does not seem to fix the problem. But restarting it works. Resetting all
connections. So if varnish could detect that it's starting to have a
problem. Reseting keep-alive would be a pretty good way of getting out of
a tight spot....
So, my feature request is acctually two things
1) Ajustable keep-alive (what is the default)
2) A way to reset keep-alive session without restarting varnish. Browses
handles that nicly. If varnish could do it itself it would be even cooler.
