This paper presents a new service to Web browsing. The service, referred to as session handoff and content sharing between two Web browsers, requires extending the capabilities of existing Web browsers by integrating a session initiation protocol (SIP) stack into them. An optional SIP application server (SIP AS) that co-ordinates HTTP session mobility between Web browsers is introduced. In addition, third-party call control and session handoff in SIP session mobility are successfully mapped to content sharing and session handoff between two Web browsers, respectively. While content sharing refers to the ability to view same Web resource on two Web browsers, session handoff refers to the ability to migrate a Web session between two Web browsers. Until now, SIP had only been integrated into application servers. Integrating a SIP stack into a Web browser has helped improve collaboration and mobility among the Web users. In addition, it encourages developing adaptive user agent clients (UACs) that can serve two or more purposes. In this case, a Web browser can also be used as a SIP client to make voice calls and be extended to perform other SIP functionalities.
