Enabling network caching of dynamic web objects

Abstract

The World Wide Web is an important infrastructure for enabling modern information-rich applications. Businesses can lose value due to lack of timely employee communication, poor employee coordination, or poor brand image with slow or unresponsive web applications. In this paper, we analyze the responsiveness of an Intranet web application, i.e., an application within the corporate firewalls. Using a new Web monitoring tool called WebMon, we found, contraryto our initial expectations, substantial variations in the responsiveness for different users of the Intranet Web application. As in the Internet, traditional caching approaches could improve the responsiveness of the Intranet web-application, as far as static objects are concerned. We provide a solution to enable network caching of dynamic web objects, which ordi-narilywould not be cached byclients and proxies. Overall, our solution significantly improved the performance of the web application and reduced the variance in the response times bythree orders of magnitude. Our cache enabling architecture can be used in other web applications. © Springer-Verlag Berlin Heidelberg 2002.
