The case for geographical push-caching

Most wide-area caching schemes are client initiated. Decisions on when and where to cache information are made without the benefit of the server´s global knowledge of the situation. We believe that the server should play a role in making these caching decisions, and we propose geographical push-caching as a way of bringing the server back into the loop. The World Wide Web is an excellent example of a wide-area system that will benefit from geographical push-caching, and we present an architecture that allows a Web server to autonomously replicate HTML pages
