cProfiles
cProfiles allows you to ADD/Remove Profiles, depending upon the potential nature of the content served, by the web-site. cProfiles queries SafeSquid's Content Categorization Service (CCS), to determine if a web-site belongs to one or more categories. The determination is actually a
score of probability: for example:
- a score of 1 ==> the site definitely does not belong to the queried category,
- a score of 100 ==> the site most definitely belongs to this category.
Now based on the determination, you can ADD / Remove Profiles, and thus take necessary actions, via the various filters like URL Filter, Mime-Filter, etc. cProfiles stores the results, in a high-speed memory based (volatile) cache, to ensure quick response for often accessed websites.
Content Categorization Service
CCS maintains a categorized database of web-sites. The categorization has been done on the basis of availability of content of certain category, at the web-site. cProfiles uses the standard DNS protocol to communicate with CCS, thus the query results will be stored (non-volatile) in all the en-route caching nameservers. Thus query results should be quickly accessible to you even across restarts.

Example
Suppose you wanted to globally block 'porn' category, and restrict 'Accounts' profiles from accessing 'jobs' category.
Create the following rules in the cProfiles section:
The first rule applies 'blocked-category' profile to all the requests, for which there is a positive match, under the 'porn' category. This rule applies to every body, since the 'Profiles' field is blank.
The second rule applies 'blocked-category' profile to all the requests, for which there is a positive match, under the 'jobs' category. This rule applies only to 'Accounts' profile.
Next, go to the URL filter section and add the following rule under Deny subsection (Presuming that the section is enabled and Policy is Allow).
This rule blocks all requests with blocked-category profile, effectively, blocking access to 'porn' category to everyone, and 'jobs' category to 'Accounts' users.
