Rules for blocking URLs

Exact match based on query strings is supported

For example, if the URL that is blocked is http://www.example.com/abc.html?a=1&b=1, only requests that are sent to http://www.example.com/abc.html?a=1&b=1 are denied. Requests are allowed to access URLs that carry different query strings, such as http://www.example.com/abc.html?a=1&b=2.
Parameters filtering is supported

If parameter filtering is enabled, and the URL that is blocked is http://www.example.com/abc.html, requests are matched against http://www.example.com/abc.html regardless of the query string. If the destination URL of a request matches http://www.example.com/abc.html, the request is denied. For example, all the following URLs are considered matches and blocked: http://www.example.com/abc.html, http://www.example.com/abc.html?a=1, http://www.example.com/abc.html?a=2, and http://www.example.com/abc.html?a=1&b=1.
