Hi all, I am doing some modifications in refresh_patterns rules in a squid host (release 3.5.20) and it seems they are working, with the exception of this one: refresh_pattern -i \.(rar|jar|gz|tgz|tar|bz2|iso|m1v|m2(v|p)|mo(d|v)|(x-|)flv) 129600 80% 129600 override-expire override-lastmod reload-into-ims ignore-reload When I run 'squid -k parse' returns me the following error: 2016/08/11 06:57:33| /etc/squid/squid.conf line 173: refresh_pattern -i \.(rar|jar|gz|tgz|tar|bz2|iso|m1v|m2(v|p)|mo(d|v)|(x-|)flv) 129600 80% 129600 override-expire override-lastmod reload-into-ims ignore-reload 2016/08/11 06:57:33| refreshAddToList: Invalid regular expression '\.(rar|jar|gz|tgz|tar|bz2|iso|m1v|m2(v|p)|mo(d|v)|(x-|)flv)': empty (sub)expression Searching where I am doing the mistake, I don't find any problem with "\.(rar|jar|gz|tgz|tar|bz2|iso|m1v|m2(v|p)|mo(d|v)|(x-|)flv)". Where am I doing the mistake?? On the other side, I see the following warnings also: 2016/08/11 06:57:33| WARNING: use of 'override-expire' in 'refresh_pattern' violates HTTP 2016/08/11 06:57:33| WARNING: use of 'override-lastmod' in 'refresh_pattern' violates HTTP 2016/08/11 06:57:33| WARNING: use of 'reload-into-ims' in 'refresh_pattern' violates HTTP 2016/08/11 06:57:33| WARNING: use of 'ignore-reload' in 'refresh_pattern' violates HTTP I have enabled these options "override-expire override-lastmod reload-into-ims ignore-reload" on some other patterns. Is this wrong?? Thanks. -- Greetings, C. L.
