[squid-users] Introducing Charcoal - Centralised URL Filter for squid

[Eliezer Croitoru]

Hey Nishant,

I want to offer you a more advanced helper that supports actual concurrency compared to the current perl helper on github,
which understands the protocol but do not use threads or any other method of concurrency.

Let me know if it's of any interest for you.
The skeleton is at:
http://wiki.squid-cache.org/EliezerCroitoru/GolangFakeHelper

I am willing to take my time and write the code for you. So..

Eliezer

Subject: [squid-users] Introducing Charcoal - Centralised URL Filter for squid

Hi,

We are excited to invite early users to test drive Charcoal
(http://charcoal.io) - a Squid URL Rewriter for distributed proxies.

Charcoal is designed to help administrators manage access rules for the proxies at just one place with a GUI, instead of editing configuration of individual proxy servers.

It has come out of our need of managing ACLs for 100+ proxy servers on embedded devices (OpenWRT/LEDE) running at our customer offices across the geography of India. We are releasing it in the hope that it will be useful for Squid users who have to manage multiple proxy servers everyday.

The architecture is API key driven client-server, where a squid url-rewrite helper contacts server to query access controls for the incoming requests.

Current features:
-----------------
- Supports Squid 2.x and 3.x
- 70+ pre-existing domains blacklist
- Custom destination groups/categories
- Custom source groups for IPs and Networks (usernames in the pipeline)
- As of now only domain filter support (no full url filtering)
- API key driven

Configuration:
--------------
- Download the helper from
https://raw.githubusercontent.com/Hopbox/charcoal-helper/master/squid/charcoal-helper.pl.
- Make sure IO::Socket module for Perl is installed.
- Add following lines to squid.conf after downloading the helper:

url_rewrite_program /path/to/charcoal-helper.pl YOUR_API_KEY url_rewrite_children X startup=Y idle=Z concurrency=1

YOUR_API_KEY for our hosted Charcoal service can be requested by filling in the form at http://charcoal.io or writing in to charcoal at hopbox.in. 
The credentials for login to https://active.charcoal.io to manage the ACL will be emailed along with YOUR_API_KEY.

License:
--------
URL Rewrite helper for squid is licensed under GPLv2.0 while Charcoal Server is licensed under AGPLv3.0.

GIT Repo:
---------
Squid URL Rewrite helper can be downloaded from https://github.com/Hopbox/charcoal-helper

Git repository for Charcoal Server is at https://github.com/Hopbox/charcoal

Regards,
Nishant
