An on demand content delivery platform for delivering on demand digital assets includes a network transport composed of network elements. A content delivery path extends from an application server, through the network transport, to a client. During content delivery, at a network element, data is inserted into the content delivery path to produce a content stream containing inserted in-stream data. In one implementation, the content is conditioned in accordance with instructions present in the in-stream data. In another implementation, the in-stream data represents session information and is utilized for stateless recovery of session information.
