1. A flow control apparatus, comprising:

  • a facility operatively coupled with a source server via a browser and a resource-constrained communications link;

    a flow control mechanism configured for selectively pre-fetching page objects from said source server and for downloading page objects in an optimally parallel fashion from said source server to said browser via said communications link;

    a cache operatively coupled with said browser that caches said pre-fetched page objects and caches page objects that are downloaded by said mechanism;

    wherein said facility is configured for enhancing said routine browser operation by;

    invoking said flow control mechanism to pre-fetch, in an optimally parallel fashion, one or more page objects that are identified as fetched according to routine browser operation, andmaking said pre-fetched page objects available to said browser by said facility before they would be if they were fetched according to routine browser operation.
