CONTENT ASSOCIATIVE CACHING METHOD FOR WEB APPLICATIONS

摘要

A cache logically disposed in a communication path between a client and a server receives a request for a content item and, in response thereto, requests from the server header information concerning the content item and an initial portion of data that makes up the content item. The cache then computes a first hashing value from the header information and a second hashing value from the initial portion of data. A content identifier is created by combining the first hashing value and the second hashing value. Using the content identifier, the cache determines whether a copy of the content item is stored by the cache; and, if so provides same to the client. Otherwise, the requests the content item from the server and, upon receipt thereof, provides it to the client.
