Abstract
A redirection of a URL page request may be performed by monitoring an upstream path from a subscriber to the internet through an ISP. When a URL page request is detected from a subscriber for whom a redirection is required, a redirection device generates a single TCP packet response that mimics a response from the intended destination server. The single TCP packet includes a set FIN bit that closes any active session with the destination server to prevent the subscriber from accepting packets from the destination server.

A method for providing a notification service to a subscriber of an Internet Service Provider (ISP) comprising:
- monitoring upstream traffic through the ISP from the subscriber;
- detecting a URL page request from the subscriber to a destination server;
- generating a redirection to the notification service in response to detection of the URL page request;
- and
- providing the redirection to the subscriber;
- wherein the redirection comprises a single packet, the single packet closing an active session between the subscriber and the destination server.
A method of redirecting a web page request from a subscriber comprising:
- generating a single TCP packet comprising redirection data and a set FIN bit;
- providing the TCP packet to the subscriber.
An Internet Service Provider comprising:
- a router;
- and
- a redirection device;
- wherein the router copies selected packets from a subscriber to the redirection device;
- and
- wherein the redirection device:
- determines from copied packets whether a redirection is required;
- generates a redirection packet comprising redirection data and a set FIN bit;
- and
- provides the redirection packet to the subscriber.
