RE: [squid-users] Squid content filtering and redirection

Thank you Helmut!

It seems to be something that I've been looking for.
Two more additional questions:

1.) You deny access to everything in "verboten" and allow only "ausnahme". In the Verboten acl you dont have to specify sites you allow access to. I mean I dont want to type in the whole internet just to allow access for sites doesn't containing words in their URL-s. So the question is: Could it be empty, and just the Deny file would contain words that is not allowed in URLs?

2.) How can you redirect? If someon trying to access a site that's been denied, what informatin will they get? It's fine if some html file is posted inside of squid or something. I can modify that, just have something to say, that the site is not allowed!

Thanks,
Tibby

One possible way:

In "squid.conf"

  # Schmuddelfilter
  include /etc/squid/conf.d/schmuddel.conf

with the file "/etc/squid/conf.d/schmuddel.conf"

  # Schmuddelfilter
  acl verboten url_regex "/etc/squid/schmuddel"
  acl ausnahme url_regex "/etc/squid/whitelist"
  http_access allow ausnahme
  http_access deny verboten

and the wordlist files "/etc/squid/schmuddel" and "/etc/squid/verboten",
one entry per line.

As far as I know "squid" can't check the contents but only can check
URLs etc.

Viele Gruesse!
Helmut
