AOP-Based Caching of Dynamic Web Content

Resumé :

Caching is an appealing approach for server-side acceleration of dynamic content web sites. Previous work in this area provides either non-transparent caching obtained at the expense of considerable effort from the application programmer, or a transparent but non-consistent caching system that does not guarantee complete consistency of cached data. We propose a new method for transparent and consistent caching of dynamically generated web pages.

We report on our experience in providing: (i) transparent caching using aspect-oriented programming (AOP), and (ii) efficient and consistent caching of dynamic content using query analysis techniques.

We have built and evaluated AutoWebCache, a caching system of dynamic web content that follows the proposed method and effectively enhances web application performance. We use two J2EE dynamic web applications to validate our experiments: the TPC-W on-line bookstore and the RUBiS auction site. In the two e-commerce applications, we show that AutoWebCache can be highly effective, reducing the response time, 97% for TPC-W and 63% for RUBiS.
