Often times, in your Squid proxy, you may have a redirector configured – such as SquidGuard:
redirect_program /usr/local/bin/squidGuard -c /usr/local/etc/squid/squidGuard.conf
I ran into a problem tonight with my Roku box where SquidGuard was seeing Roku’s NetFlix access as a security threat. So, to make Squid bypass the redirector, add an ACL and a redirector-access rule:
acl netflix dstdomain .netflix.com redirector_access deny netflix
There you have it – any requests to *.netflix.com will skip the redirector.
