Abstract: Browser sharing technology, i.e., sharing a window of a web browser or a portion thereof. This browser sharing is lightweight, in that it does not require the installation of a thick or thin client. The browser downloads and executes code to facilitate browser sharing in the same way that it downloads and interprets HTML for webpage rendering. Embodiments of the present invention permit all of the viewers of the shared browser window to interact with the window as it is shared, and their interactions appear concurrently in all of views.
