document: Co-browsing dynamic web pages Collaborative browsing , or co-browsing , is the co-navigation of the web with other people at-a-distance , supported by software that takes care of synchronizing the browsers . Current state-of-the-art solutions are able to do co-browsing of `` static web pages '' , and do not support the synchronization of JavaScript interactions . However , currently many web pages use JavaScript and Ajax techniques to create highly dynamic and interactive web applications . In this paper , we describe two approaches for co-browsing that both support the synchronization of the JavaScript and Ajax interactions of dynamic web pages . One approach is based on synchronizing the output of the JavaScript engine by sending over the changes made on the DOM tree . The other approach is based on synchronizing the input of the JavaScript engine by synchronizing UI events and incoming data . Since the latter solution offers a better user experience and is more scalable , it is elaborated in more detail . An important aspect of both approaches is that they operate at the DOM level . Therefore , the client-side can be implemented in JavaScript and no browser extensions are required . To the best of the authors ' knowledge this is the first DOM-level co-browsing solution that also enables co-browsing of the dynamic interaction parts of web pages . The presented co-browsing solution has been implemented in a research demonstrator which allows users to do co-browsing of web-applications on browser-based networked televisions .
