It filters using multiple methods. These methods include URL and domain filtering, content phrase filtering, PICS filtering, MIME filtering, file extension filtering, POST limiting."

ProxyPass

Despite the name, ProxyPass has nothing to do with the Squid proxy and is actually an Apache directive designed to allow a given URL on your server to return the content of some other webserver - either internal (behind your SME) or external.

Customizing Squid

Bypass the Proxy Server Without Disabling Your Transparent Proxy

     mkdir -p /etc/e-smith/templates-custom/etc/rc.d/init.d/masq
     cd /etc/e-smith/templates-custom/etc/rc.d/init.d/masq
     wget -O 35transproxy http://bugs.contribs.org/attachment.cgi?id=1191
     wget -O 90adjustTransProxy http://bugs.contribs.org/attachment.cgi?id=1192
     config setprop squid BypassProxyTo a.b.c.d
     expand-template /etc/rc.d/init.d/masq
     service masq restart

• Replace a.b.c.d with the IP or network address for which you wish to bypass the proxy server.
• Use config setprop squid BypassProxyFrom a.b.c.d to configure a specific local host or network that should bypass the proxy server
• Note that 'signal-event remoteaccess-update' does not seem to completely rebuild /etc/rc.d/init.d/masq
• Be sure to check the bug for changes to the attachments: http://bugs.contribs.org/show_bug.cgi?id=2374)

Disable squid proxy bypass using:

config delprop squid BypassProxyFrom
config delprop squid BypassProxyTo
expand-template /etc/rc.d/init.d/masq
service masq restart
