Re: [squid-users] Squid takes too long to stop.

Hello,

I have a load balancer in front of two Squids in a reverse proxy setup.
The load balancer decides whether a Squid is healthy by opening a TCP
connection to it periodically. During the shutdown interval governed by
configuration parameter 'shutdown_lifetime', Squid 2.5 STABLE12
continues accepting connection requests and responding to each request
with status code 503. The load balancer interprets this as "healthy". I
would prefer instead that Squid continue servicing pending requests on
open connections, but refuse new connection requests so that the load
balancer could do its thing and route to the other Squid for
uninterrupted service. Is there any way to achieve this in Squid 2.5
STABLE12 or later?

Thanks,
Ben
