Web applications have come a long way, both in terms of adoption to provide information and services, and in terms of the technologies to develop them. With the emergence of richer and more advanced technologies such as AJAX, web applications have become more interac-tive, responsive and user friendly. These ap-plications, often called Rich Internet Applica-tions (RIAs), changed the web applications in two ways: (1) dynamic manipulation of client-side state and (2) asynchronous communica-tion with the server. However, at the same time, such techniques also introduced new chal-lenges. One important challenge is the diffi-culty of automatically crawling these new ap-plications. Without crawling, RIAs cannot be indexed nor tested automatically. Traditional Copyright c © IBM Canada Ltd., 2012.

This paper surveys the research on addressing the problem of crawling RIAs and provides some experimental results to com-pare existing crawling strategies. In addition, we provide some future directions for research on crawling RIAs. 1
