Note that squid has filtering capabilities, but isn't, of and by itself,
a filter.


  - Filters known sites based on criteria (sex/porn, games, gambling,
    etc.)  You can pick which categories are or are not allowed.

  - Offers context/content filters based on weighted keywords.  A given
    word might not be sufficient to block a page by itself.  In context
    with other words, its score might be raised or lowered.

  - Self-reported site classifications.  I forget the particulars of the
    system, but it's a way for website authors to self-report as
    family-safe or not, by various classifications.

  - Filetype and extension-based blocking.

  - Copious options for customization to allow/disallow sites based on
    additional criteria.

I say use the right tool for the job, and Dansguardian is more so than

That said:  the configuration I referred to used both DG *and* Squid.
DG provided filtering, Squid provided caching.  Bought us an 80%
bandwidth reduction to boot.
