1. A method of data delivery, comprising:

  • at a server executing on a hardware platform;

    receiving, from a client and over a persistent 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 security token and identifying an IP address and UDP port number associated with the server, the response body being devoid of the content object requested;

    receiving from the client a UDP request directed to the IP address and UDP port number, the UDP request associated with a SYN UDP packet indicating a request to initiate a UDP connection and including an initial sequence number;

    verifying that the UDP request includes the security token; and

    upon a successful verification, returning a response to the UDP request over the UDP connection that includes a SYN ACK packet acknowledging the SYN UDP packet and including the initial sequence number, together with the content object that was identified in the HTTP request but not returned in the response body.
