This is a dummy URL command designed for test suite. Each CGI program has its own dummy URL command. Some WEB browsers will not send URL commands if they are in the browser's cache. The browser will return the URLs from its cache. That causes the configurations between browser and device are not in sync.
This URL helps to avoid this kind of problem. The host could append this DUMMY URL with a random number. The browser will treat every URL as the new URL.
