1. A method comprising:
detecting, by an insertion server running within a firewall device associated with a private Internet Protocol (IP) network, establishment of a transport communication protocol connection between a client device associated with the private IP network and a destination device located external to the private IP network by examining packets, by the insertion server, as they pass through the private IP network and pass by the insertion server; observing, by the insertion server, a content request of an application protocol initiated by the client device and directed to the destination device; negating the content request, by the insertion server, by causing a canceling message of the transport communication protocol to be sent to the destination device; causing, by the insertion server, unsolicited content to be selected for delivery to the client device; and sending, by the insertion server, the selected unsolicited content to the client device via the application protocol. |
