Squid Windows Update regular expression
-
We are running pfSense 2.0-RC3 (and most recent updates), along with Squid 2.7.9_4.1. We are trying to get Windows Updates to cache and tried the rule shown in the Wiki docs. We get the following message in /var/squid/log/cache.log when we try to use that rule (as it appears others are):
2011/06/30 16:08:17| parse_refreshpattern: Invalid regular expression '([^.]+.|)(download|(windows|)update|).(microsoft.|)com/.*.(cab|exe|msi|msp)': empty (sub)expression
Using a web based regex parser it appears to be a valid pattern. Does anybody have a solution to this? Is there any way to have squid give us more detail on what it does not like about that expression?
Thanks!

I have the same problem.

Try this:
refresh_pattern -i .*microsoft\.com/.*\.(cab|exe|msi|msp) 129600 100% 129600 override-expire override-lastmod reload-into-ims ignore-reload ignore-no-cache ignore-private; refresh_pattern -i .*windowsupdate\.com/.*\.(cab|exe|msi|msp) 129600 100% 129600 override-expire override-lastmod reload-into-ims ignore-reload ignore-no-cache ignore-private;–-edit---
Did you post the whole line ?
there is the time missing 1440 100% 1440 and then the subexpressions like reload-into-ims -
Finally, I modified the regexp to:
refresh_pattern ([^.]+.)?(download|(windows)?update).(microsoft.)?com/.*.(cab|exe|msi|msp|psf) 4320 100% 43200 reload-into-ims;range_offset_limit -1;
