I'm testing Squid 3.2.3 and seem to be encountering some sort of "timeout" problem on browsers. When left idle for long periods (hours), Firefox and IE9 seem to "lose" the connection, and can only be resolved by restarting the browser.
The squid.conf is more or less the standard copy from the installation, and I have not added anything that looks like a "timeout" parameter. I've never seen this in previous versions I've used, 2.6 and 3.1. What might it be?
