Cache hinting systems

摘要

The present invention relates to systems, apparatus, and methods for improving web transactions using cache hints. In various embodiments, cache hints may be information for optimizing and extending the use of cached objects based on web transaction information from system users. This may enable indirect updates to caching directives, and may allow a proxy to respond to If-None-Match or If-Modified-Since requests using information from cache hints instead of prefetched information from a content provider.

主权项

1. A method comprising:
receiving, at a cache hinting system comprising a browsing assistance computing device, a set of web transaction information, wherein the set of web transaction information is created in response to an observation of an object as part of at least a portion of a first web transaction including an HTTP (hypertext transport protocol) response from a content server to a client computing device, and wherein the HTTP response comprises caching instructions for the object; updating, by the cache hinting system, a set of cache hints associated with the object using the set of web transaction information; receiving, by the cache hinting system, a request for hint information from a second client computing device; and communicating the set of cache hints to the second client computing device.
