Is this wrong?? Those are WARNINGs. Not an error. They instruct Squid to do things which are outside the HTTP specification. You may encounter trouble with some traffic because of that changed behaviour. The warnings are there to make sure you awre aware something risky is being done, and when you run into trouble with those options it is probably not Squid bugs but your choice to violate the standard HTTP behaviour which caused it.

[squid-users] A problem with a refresh pattern rule
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. Martinez ___ squid-users mailing list squid-users@lists.squid-cache.org http://lists.squid-cache.org/listinfo/squid-users
