Dependable web page synchronization mechanism

摘要

Described is a mechanism for dependably synchronizing web pages among a group of browsers. Each of the web page embeds an applet. In response the activities (such as loading or unloading of a web page) performed at a browser, the applet reports activities (together with the URL of the web page) to a page synchronizing server, which in turn relays the activities (together with the URL) to all participant browsers. The participant browsers can load and unload the web page according to the report of the activities.
