An approach is provided for supporting retrieval of a web page over a data
network from a web site is disclosed. A downstream proxy communicating
with a host executing a browser receives a request message from a browser
to retrieve the web page. An upstream proxy parses the web page to
determine an object embedded in the web page, wherein a promise list is
generated specifying the embedded object that is to be pre-fetched
according to a criterion. The promise list is transmitted to the
downstream proxy, wherein the upstream proxy pre-fetches the embedded
object from the web site. The upstream proxy determines whether to
forward one of the pre-fetched embedded object to the downstream proxy
based on a comparison of cookies associated with one of the pre-fetched
objects supplied, respectively, by the browser and the web site. This
approach as particular applicability in relatively high latency networks,
such as a satellite communications system.
