[squid-users] SquidGuard cgi problem

Hello all,

I have been using squid / squidGuard for so long now that I have
completely forgotten how I set it up!

Now, following a recent upgrade to SQUID 3.0.STABLE20 I find that the
squidGuard redirect page fails with the error:
"You don't have permission to access /cgi-bin/squidGuard.cgi on this
server"

My first action was to check the permissions of that file:
# ls -la /var/www/cgi-bin/squidGuard.cgi
-rwxr-xr-x. 1 root root 11169 2009-08-17 19:34 /var/www/cgi-bin/squidGuard.cgi

Which is, I think, how it was when it was still working. Just in case it
had anything to do with users I "chown'ed" it to squid.

# ls -la /var/www/cgi-bin/squidGuard.cgi
-rwxr-xr-x. 1 squid squid 11169 2009-08-17 19:34 /var/www/cgi-bin/squidGuard.cgi

Still no joy.

I can access the squidGuard.cgi file directly from a browser on a
machine on the network so actually I'm sure it's not a permission
problem. It's only when called from squid / squidGuard that I get the
error.

In my squid.conf I do have "cache_effective_user squid" set.

I know I'm missing something silly - what have I forgotten to do or
check?

Thanks in advance for any help or suggestions...

Mark
