Set by a present WJA system. Once set, the WJD user interface will add a framework link from the WJD navigation bar. This link will allow user navigation to the highest level page of WJA. This will allow users to easily navigate to WJA to manage other devices with the network. Since the URL can become stale, it is required that the WJD code verifies that the URL is active before actually using it. This is required since the WJA system may not always be operable. Maximum length of the url must be less than 255 bytes.
