Re: [squid-users] Squid 3.4 refresh_pattern bungled config

Thanks for highlighting this. I have the same problem on FreeBSD 9.1
with same version of Squid, compiled from source. A config file that
works with 3.3.8 does not work with 3.4.0.1 because of the refresh
patterns. Unfortunately, it seems my post about that did not get the
attention of Amos, Eliezer,etc.
