1. A method for processing file requests for files maintained in a server that are capable of being accessed from the server over a network, comprising:

  • receiving a request for a file maintained in the server;

    determining whether a copy of the requested file is stored in a storage system;

    determining a delay time associated with retrieving the copy of the requested file from the storage system after determining that the storage system includes the copy of the requested file;

    determining whether the delay time exceeds a maximum delay time;

    determining a network response time to retrieve the requested file from the server over the network;

    retrieving the requested file from the storage system to return to the request after determining that the delay time does not exceed the maximum delay time;

    retrieving the requested file from the storage system when the delay time is greater than the maximum delay time if the network response time is greater than the maximum delay time; and

    retrieving the requested file from the server over the network to return to the request after determining that the delay time exceeds the maximum delay time.
