Server-side detection and mitigation of client-side content filters

Abstract:

A server-side technique to detect and mitigate client-side content filtering, such as ad blocking. In operation, the technique operates on a server-side of a client-server communication path to provide real-time detect the existence of a client filter (e.g., an ad blocker plug-in) through transparent request exchanges, and then to mitigate (defeat) that filter through one or operations designed to modify the HTML response body or otherwise obscure URLs. Preferably, the publisher (the CDN customer) defines one or more criteria of the page resources being served by the overlay (CDN) and that need to be protected against the client-side filtering.
