Selective prefetch scanning

摘要

The present invention relates to systems, apparatus, and methods of enhancing prefetcher functionality by scanning responses object requests. In certain embodiments, prefetching is improved by identifying references to container objects or sections of container objects at a proxy server. When URLs are identified as part of a container object, a prefetching determination or adjustment to a prefetching decision is made according to the identification of the reference for a subset of URLs identified by the reference to the container object. For example, prefetching of URLs located in cascading style sheet (CSS) files may be restricted to a subset of URLs which are identified by a CSS rule.

1. A method for selective prefetch scanning in a web client/server communications system connecting a web client and a web server, the method comprising:
scanning a first response at a prefetcher; identifying, in the first response, a reference to a first section of a container object, wherein the container object includes a set of uniform resource locators (URLs) and the reference to the first section of the container object identifies a subset of the set of URLs; scanning a second response comprising the container object and the reference by a container object scanner of the web/client server communication system; determining whether the reference substantially matches one of a collection of recently applied references stored in an applied reference store communicatively coupled with the container object scanner; and when the reference substantially matches one of the stored collection of recently applied references, adjusting a first prefetch decision for the subset of the set of URLs.
