Abstract

AJAX is a very promising approach for improving rich interactivity and responsiveness of web applications. At the same time, AJAX techniques increase the totality of the hidden web by shattering the metaphor of a web ‘page’ upon which general search engines are based. This paper describes a technique for exposing the hidden web content behind AJAX by automatically creating a traditional multi-page instance. In particular we propose a method for crawling AJAX applications and building a state-flow graph modeling the various navigation paths and states within an AJAX application. This model is used to generate linked static HTML pages and a corresponding Sitemap. We present our tool called CRAWLJAX which implements the concepts discussed in this paper. Additionally, we present a case study in which we apply our approach to two AJAX applications and elaborate on the obtained results.
