EXTENDED HTTP OBJECT CACHE SYSTEM AND METHOD

摘要

An Extended Object Cache system for reducing network traffic and methods for making and using the same. The Extended Object Cache system allows caching of HTTP responses where the response headers do not include Etag headers to indicate whether contents of the response have changed, but the contents have not changed. The system allows caching of dynamically generated content as well as static content that does not include an ETag in the response headers.

1. A method for reducing network traffic between an application and a destination server, comprising:
intercepting a network request from the application via a client proxy; forwarding the network request to a server proxy; receiving a network response from the destination server at the server proxy; determining at the server proxy whether the network response is the same as a cached response at the client proxy; and transmitting a ‘304 Act Not Modified’ response to the client proxy if the cached response at the client proxy is the same as the network response, otherwise transmitting the network response to the client proxy to transmit the network response to the application.
