Patent ID: 8208375

Claim:
A method of selectively filtering network traffic, comprising: receiving, on a client computing device, an initial request for network-accessible content generated by a networking program on said client computing device; determining whether said initial request is allowable by a filtering service on said client computing device that is configured to monitor said networking program; generating, by said filtering service, a special identifier corresponding to said initial request if said initial request is allowable with reference to a filtering policy; passing, by said filtering service, identifier to an application or object installed on said client computing device that is configured to intercept requests for network-accessible content generated by said networking program and to include said special identifier corresponding to said initial request in subsequent requests for network-accessible content intercepted from said networking program which are related to said initial request for network-accessible content; receiving, at said filtering service, a subsequent request for network-accessible content generated by said networking program; and allowing, by said filtering service, said subsequent request without reference to said filtering policy if said subsequent request includes said special identifier corresponding to said initial request.
