The present invention relates to embedded HTML documents and to a method and system for rendering such documents to a visual display unit. The Internet does not currently support embedded documents. The current manner of viewing a plurality of HTML documents is to include a URL within one documents which allows access to a second document. HTML does not provide for the nesting or embedding of HTML documents. Accordingly the present invention provides a system and method for realising embedded HTML documents. The present invention utilises a Java applet which can be launched by a Java enabled browser. The Java applet can parse and render HTML instructions contained within an HTML document to a reserved area of a visual display unit. The Java applet can also launch further applets and therefore allow further nesting or embedding of HTML documents.
