Any web page URL.
Any time a player in a room presses 'F8', the Challenge Maze Software will attempt to launch the web page URL.   The Challenge Maze Softwre will attempt to do this by sending a message to the computer operating system telling the computer that it wants to launch a web page. Most of the time, the computer will respond by attempting to open the web page in the default browser of the computer. Any Web Page URL must begin with the prefix 'www.' or the prefix 'http://'. If the URL does not begin with either of those two prefixes, the attempt to launch the web page will generally fail.
