Url Blacklist

URL Blacklist

This section allows you to use any flat-file URL blacklist databases, like the ones obtained from http://www.shallalist.de/ and http://www.urlblacklist.com/ to restrict access to websites based on content category like porn, adult, webmail, jobsearch, entertainment, etc. These sites maintain a well categorized list of various websites and pages. This is an excellent resource for an administrator seeking granularity in enforcing a corporate policy that allows or disallows only certain kinds of web-sites to be accessible by specific users, groups or networks.

NOTE: SafeSquid has its own real-time website categorization service - cProfiles. Unlike traditional URL Blacklists that only allow you to block or allow access to websites based on their categories, cProfiles allows you to take a variety of actions. For example, block cookies if a website belongs to 'Ads' category, allow 'Social' category only between 1pm to 2pm, allow 'Multimedia' category only at 5 kbps, etc.

Blacklist path

Please note that the complete database is loaded into the system memory, when SafeSquid service starts. If you plan to use only specific categories, then copy only those category directories in this location. This will help save memory resources, which would otherwise be unnecessarily used up by unwanted categories.
Default template

Allow / Deny Subsection

You can define rules either under the Allow or Deny subsection, depending on the selected Policy. If Policy is Allow, you should define rules under the Deny subsection, and If Policy is Deny, you should define rules under the Allow subsection. In the above example, the Policy is Allow. Hence, rules are defined in the Deny subsection to deny access to adult, porn and jobsearch categories.
