Abstract
A network device is deployed in an in-line fashion, preferably at a data traffic point along a network. Depending on the constraints of data packets in a data packet sequence from a website, the network device is configured to modify some of the data packets or fabricate new data packets to embed the selected data in the data packet sequence. By keeping the headers of the data packets substantially identical, changes to a data packet or addition of a new data packet become transparent to users as well as to the website.
