Dependable data element synchronization mechanism

摘要

Described is a mechanism for dependably synchronizing data element activities on web pages among a group of browsers. The web browsers retrieve web pages from an HTTP server. Each of the web pages contains at least one data element and embeds a Master Applet and at least one DTS Applet (DTS stands for data tracking and synchronization). In response the data element activities (such as entering data into a data field) performed at a browser, the DTS Applet passes the activities to the Master Applet, which in turn reports the activities (together with the URL of the web page on which the data element activities have occurred) to a tracking server. The tracking server sends the activity report (together with the URL of the web page on which the data element activities have occurred) to the Master Applets at all participant browsers. The participant Master Applets then instruct their respective DTS Applets to display the data element activities on the web page identified by the URL.
