[squid-users] Re: AdZap: WARNING: Cannot run '/usr/local/bin/squid_redirect' process.

I've tried replacing the AdZap's squid_redirect script by a simple
redirector from http://wiki.squid-cache.org/faq/redirectors and
have the same problem. So it isn't AdZap's fault.

Is running Squid in transparent mode AND using redirect_programs
possible?
