Abstract
Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. One or more controllers connect the users or collaborators in a session in the server system. This is realized by establishing a so-called “shared Web-top”, i.e., a work space, in which different in-document applications can be run and can be interactively, collaboratively shared by a plurality of users. Specifically, this is realized in one embodiment by employing event handlers in the WEB documents that are activated whenever there is a change in the values of prescribed properties of a document. The event handlers notify a so-called surrogate of the changes in the prescribed properties of the document, i.e., that values in elements of a form have changed, and transmit the detected changes to surrogates of other users, i.e., at least one other collaborator, via a communication channel. To this end, a prospective user of the shared Web-top accesses a system that transmits mobile code to the user's computer to create a surrogate thereon. The surrogates created for the users of the shared Web-top are connected by at l…
