When I tried that (not sure which version; 1.1.something or 1.NOVM.something;
whatever was current a month or two ago...), it looked as though HUP was not
enough. Either that, or the cachemgr display showed the old cache size even
though Squid was actually using more space as specified in the updated
configuration - the Max Swap size that was displayed was the pre-edit value.
When I restarted Squid, the cache.log entries showed it was using the new size.
