1. A method of enhancing prefetch operations, the method comprising:

  • storing, at a client-side proxy, a first object;

    receiving, at the client-side proxy, a prefetched object valid response to a prefetch validity check comprising a first object validity check associated with the first object;

    storing at the client-side proxy the prefetched object valid response and associating the stored prefetched object valid response with the first object;

    identifying at the client-side proxy, a request for the first object from a client;

    determining, at the client-side proxy, whether the request for the first object from the client includes a second object validity check;

    responsive to determining that the request for the first object from the client does not include the second object validity check, generating a request fulfilled response based on the stored prefetched object valid response; and

    serving the first object from the client-side proxy to the client with the request fulfilled response.
