I would like to be shown how to block OR allow (I'm not fussed either way, I beleive I can transpose the answer to what I want to do) based upon a google search query (submitted by the user). The key here being the google search term i want to be able create an ACL for. Not just the google web-site.
So... you want a filter which people can either bypass it trivially by
browsing from google search results. Or if they do need to use google
will automatically block anything they do from then on?
Good luck.
So going forth with the blacklist-whitelist example (the further complicated one), how would I achieve a pattern that matches and allows "pirates of penzance" but denies occurences of "pirate"?
whitelist:
pirates.of.penzance
blacklist:
pirates
I have read through the FAQ but I don't believe this exact scenario is covered in depth.

Also to show I have tried, I have come up with a url_regex pattern in my file like so:
q=pirates
It would be much better though if I could make this a bit more semantic by including the google domain in there and being able to include spaces in the pattern.
Sounds like you are using regex patterns without understanding how they
work. Look it up. http://google.com/search?q=Perl+regular+expressions

Hi,
Just wondering if there is a way of getting squid to block or allow based on google search results.
That sentence makes no sense to me whatsoever. Can you explain it a bit?
What are you intending to get out of it?
I have tried setting two
url_regex -i "file/path/goes/here"
one for allowed and one for blocked.
if
I set http://www.google.com to be allowed then unwanted words can be
searched and their results displayed. Clicking on said results displays
error/blocked page.
If I remove http://www.google.com then I can't search on some words that I want.
Example:
I would like to search on "pirates of penzance" but cannot because "pirate" is a keyword in my block list.
Is
there a better way around this? I don't want to (and can't) install
other software like squid-guard and dans guardian. I'm hoping to do
this in squid alone.
You describe a perfectly working URL keyword filter.
- whitelisting "google.com" ... allows *ALL* of google.com.
- blacklisting *pirate* ... blocks *ALL* mentions of "pirate" in URL
(including google lookup URLs, result URLs, etc)
Your choices are:
* accept the price of keyword filtering URLs.
* stop using the filter.
* complicate your config further with a set of
whitelisted-blacklisted keywords based on other things (like your
google.com example).
