1. A secure method of synchronizing cache contents of a mobile browser with a server, comprising:

  • initiating a session between said browser and server, said session conforming to an out-of-band protocol, including transmission of browser state information regarding said cache contents and an authentication key to said server, said browser state information being in the form of a hash value;

    maintaining a record of data sent from the server to the browser for storage in said cache;

    maintaining a record of said state information regarding said cache contents transmitted from the browser to said server; and

    transmitting data requests from said browser to said server, in response to which said server uses said authentication key to generate a message authentication code that includes a cryptographic hash of data, and accesses each said record of data and returns only data that does not already form part of said cache contents, and wherein said returned data includes a result of a hash of data generated using said authentication key for authentication by said browser before updating the cache contents with said data.
