I'm looking at deploying Squid with filtering using malware blacklists from www.bleedingsnort.com www.malware.com.br www.shadowserver.org/cc.php and possibly some other limited blacklists. We will only be filtering for malware/spyware etc.. No other content filtering is required, so we want to avoid using SquidGuard or similar. The shadowserver.org and bleedingsnort.com lists could easily be integrated as dstdomain acl, but the malware.com.br is a regex_url list and I don't want to take the performance hit using a regex_url acl. So the idea was to try and use a redirector like asqredir for the regex_url files. I also want to use the dnsbl_redir to check dns blacklists (which potentially could replace the dstdomain acl as well if that is of any performance benefit). Problem is to use the two redirectors at the same time. If we used dnsbl_redir as an external_acl_type (after some modification) and leave asqredir as the redirector, we should be in business? I expect the dnsbl_redir has a lower overhead as a helper application than asqredir would if changed into a external acl helper, or does that not matter? Have anyone tried this? Both the asqredir and dnsbl_redir compile under cygwin, so it doesn't seem to be a problem to get the to work with the windows version of squid, which is a requirement for us (although we have only done some basic testing on it).
