[squid-users] A problem with a refresh pattern rule

[C. L. Martinez]

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.
