Abstract

A system and method for updating page content of a web page includes applying a partial page update from a content server to the page content through a proxy content element. This avoids having to reload the entire page content every time a change to content is required; thus eliminating screen flash within the browser, which generally accompanies navigating between similar pages from the same web site.
