SYSTEM AND METHOD FOR COMMUNICATING STATE MANAGEMENT BETWEEN A BROWSER USER-AGENT AND A SERVER

摘要

A method of controlling delivery of content from an origin server to a mobile device browser via a proxy server, comprising: transmitting state information from the mobile device browser to the proxy server indicative of cached content and associated expiry headers (21); retrieving data (23) from said origin server to said proxy server responsive to a request from said mobile device browser; and forwarding said data from said proxy server to said mobile device browser only in the event that said state information indicates that said mobile device has not already cached said data (33) and otherwise indicating to said mobile device browser that said data is already cached (31) and transmitting new expiry headers to the mobile device browser whereupon the browser performs a cache update with said new expiry headers.
