Claim 0:
1. A method of data delivery, comprising:
at one or more servers executing on a hardware platform:
receiving, from a client and over a connection, an HTTP request that identifies a content object;
returning to the client a response to the HTTP request that includes a header and a response body, the header including a multicast group address, the response body being devoid of the content object requested;
receiving from the client a UDP request directed to the multicast group address; and
returning a response to the UDP request, the response comprising multicast UDP packets comprising the content object, together with information useful to decode the content object, the multicast UDP packets being returned in response to the UDP request for a demand-based amount of time and at a pre-configured rate;
wherein the demand-based amount of time represents a duration for sending the multicast UDP packets to the multicast group addresses, the duration being dynamically extended as long as there are incoming UDP requests for the content object.
