Hi Jonathon,

The error only shows up in syslog.  I think the problem is that my
system regex documentation is incorrect, and squidGuard was built with
only basic regular expression support from libc.

If i use a redirect (r on the end of the expression), i see the
literal \1 exposed in the browser URL, too.

Unfortunately, Google's default safesearch is moderate, and i want it
to be strict.  Even with moderate strict search on, a simple search
like "porn" ends up with lots of undesirable text on student screens.

One tactic i've had recommended is to block google completely unless
it has '&safe=strict' in it, then provide a search button on your
intranet that does this.  That seems overkill to me, as there should
be a way to do this.  I might have to look into squirm or something
like that instead.
