Abstract
Disclosed is a technique for pre-emptive URL filtering. A filtering engine may be configured to receive an original set of URLs from a web server along with a main content, the original set of URLs and the main content being intended for a web browser running in a client computer. The filtering engine may be running in a gateway. The filtering engine may check the original set of URLs for blocked URLs. The filtering engine may create a reconstructed set of URLs that suppresses blocked URLs in the original set of URLs. The filtering engine may send the client computer the reconstructed, instead of the original, set of URLs. This advantageously cuts down on the number of HTTP connections that have to be made by the browser, and corresponding URL filtering at the gateway, in situations where there is a blocked URL in the original URL set.
