Caching static web pages in proxy caches has reduced bandwidth consumption and retrieval latency. However, web-caching performance is hard to increase further due to the growing number of non-cacheable dynamic web pages. In this paper, we present TeCaS, a transparent template caching system that uses template, delta and compression to increase the performance of dynamic web traffic. TeCaS has four advantages. First, its transparent to both clients and web servers, and is independent on the web technologies used by web servers. Second, template has high reusability and small storage requirements. Third, it has reasonable computation overheads. Fourth, it has no privacy or security concerns. Extensive experimental results show that TeCaS can reduce retrieval time by a factor of 3.46 to 17.37 for dynamic web pages, without suffering from significant computation overheads or storage requirements.
