Abstract


With the rapid development of Internet, has now entered the era of Web2.0. Based on Web2.0 technology, is to enhance user involvement is characterized as user participation in content creation and collaborative development convenience. Collaborative browsing through the Web technology will be located in different regions, different areas of research people together to jointly participate in content creation, collaborative browsing this order, represented by the JavaScript engine synchronization application supporting technology has become a research hotspot. In this paper, existing collaborative browsing support for dynamic page weaker problem, first of all, by analyzing the collaborative browsing architecture and related technology, combined with dynamic Web pages acceleration method is proposed based template engine mechanism collaborative browsing architecture that the DOM-based level input synchronization mechanisms JavaScript engine and template engine mechanism composed of two parts. Using a template engine mechanism to effectively promote co-browsing of the dynamic interaction; DOM-based JavaScript engine input level synchronization mechanisms to achieve synchronization between users UI events. Compared with the traditional co-browsing system, the architecture of the real-time interaction is strong, co-browsing, faster response. Then, through the existing Web pages and page rendering synchronization methods, this paper proposes a DOM-based JavaScript engine input level synchronization mechanisms. The synchronization mechanism can achieve a better user participation in the process of co-browsing UI event synchronization to ensure that all participants simultaneously displayed within the browser page. Compared with the conventional synchronization mechanism, the mechanism has better scalability and better user experience. Next, co-browsing application template file large, and real-time dynamic small and frequent interaction data, etc., was proposed based on combination of server and client Duanxiang template engine optimization strategies: the server-side page generation task sharing migrate to the client browser device, breaking the template tag technology, client-side template cache validation mechanism filling technology and other technologies. The improved template engine can effectively improve the network transmission efficiency and reduce the load on the Web server. Finally, open-source software in 863 countries collaborative platform - Trac platform to achieve a template-based mechanism for collaborative browsing engine prototype system, and for co-browsing system response time, network traffic and server systems, data throughput and other aspects of Test results show that the template engine based collaborative browsing system in the overall response rate has greatly improved. Paper work is completed 863 project \
