* connecting applications. The client passes the token in a special header
* and the request is permitted.
*
* The file consists of a JSON object in the following format:
*
* @code
* {
* "token": "{8a34d0f0-29d0-4e54-b3aa-ce8f8ad65527}"
* }
* @endcode
*
* Additional data can be added to the object using the setData() method.
