Re: [squid-users] Invoked sites by allowed websites.
So this is what I have now, and the way I see it, it says allow all goodsites and sites that have referers, but it still doesn't appear to work properly. acl goodsites dstdom_regex "/etc/squid/allowed-sites.squid" acl has_referer referer_regex . http_access allow goodsites has_referer On Dec 14, 2007, at 2:21 PM, Henrik Nordstrom wrote: On fre, 2007-12-14 at 11:45 -0600, Cody Jarrett wrote: I think I almost have it.

I think I almost have it. I can access sites in my allowed file.

[squid-users] Invoked sites by allowed websites.
I'm using squid 2.6 and have it configured to block all websites except for a few that I specify are ok. The problem I'm having is, several sites that are fine to access, such as kbb.com, have content invoked from other sites. So when I view kbb.com for example, the page is missing most it's content and looks really messed up in firefox, and this happens with other sites.
