Using Browser Protection and Web Filtering
Authorize and prohibit sites by URL or domain
How site patterns work
The Exceptions list uses site patterns to specify a range of sites that are authorized or prohibited. This
enables you to authorize or prohibit a particular domain or a range of similar sites without entering
each URL separately.
When a client computer attempts to navigate to a site, browser protection checks whether the URL
matches any site patterns configured in the Exceptions list. It uses specific criteria to determine a match.
A site pattern consists of a URL or partial URL, which browser protection interprets as two distinct
sections: domain and path.
Site pattern: www.mcafee.com/us/enterprise
http://
www.mcafee.com
/us/enterprise
Site patterns must be at last six characters in length, and they do not accept wildcard characters.
Browser protection does not check for matches in the middle or end of URLs.
Use the "." character at the beginning of a site pattern to match a specific domain. For convenience,
the "." character disregards the protocol and introductory characters.
Example: .mcafee.com

This is the domain. The domain consists of two parts:
• Protocol. In this case: http://
• Internet domain. In this case: www.mcafee.com
Domain information is matched from the end. A matching URL's domain
must end with the site pattern's domain. The protocol can vary.
These domains match:
• http:// ftp.mcafee.com
• https://mcafee.com
• http://www.info.mcafee.com
These domains do not match:
• http:// www.mcafee.downloads.com
• http://mcafee.net
• http://www.mcafeeasap.com
• http://us.mcafee.com
This is the path. The path includes everything that follows the / after the
domain.
Path information is matched from the beginning. A matching URL's path
must begin with the site pattern's path.
These paths match:
• /us/enterpriseproducts
• /us/enterprise/products/security
These paths do not match:
• /emea/enterprise
• /info/us/enterprise
