Abstract
A Program product code, a method, and a deviceare disclosed for an enhanced caching and mirroring router which modifies stored web pages in order to indicate the age, time of capture, and which allows requests for a new copy of the page. By incorporating an HTML modification Java servlet into the caching router, the caching router can efficiently merge the cached web pages with local data objects, such time stamps and age counters, in a real-time manner, thereby providing the receiving user with an indication of the time and/or age of the cached page, where there would otherwise be no indication to the user of the age of the web page. In an enhancement of the invention, a method is provided to detect a refresh request from the user in order to fetch a new, current copy of the cached page.
