Squid block site except for some pages

Question

I have Squid proxy server installed on my machine. I created a file /etc/squid/block.acl, where all the bad domains are written. And added the following statement to squid.conf:

acl bad_url url_regex "/etc/squid/block.acl"
http_access deny bad_url

Suppose, there is a domain: finam.ru. I want to block access to all its pages, except for these pages: finam.ru/analysis/*

How to do it? I tried regexp, but it doesn't work.

Answer 1

1. Create a file /etc/squid/white.acl

2. Put the following data there:

   finam.ru/analysis/.*
   finam.ru/.*\.js
   finam.ru/.*\.css
   

3. Put this code into squid.conf. You have to put the whitelist before the blacklist:

   acl good_url url_regex "/etc/squid/white.acl"
   http_access allow good_url
   
   acl bad_url url_regex "/etc/squid/block.acl"
   http_access deny bad_url
