URI Event Types.
Each of these events is caused by an http request to a minimal web server, these are genarally used to generate actions from user interfaces. This web server will normallt be running on a non standard http port so that the main web server can still function.
The event type is http://id.webbrick.co.uk/events/uri
The event source will be the requested object from the http request. i.e. if the uri is typed into a browser as http://localhost:8085/home/courtesy then the event source will be '/home/courtesy'.
The other data is gleaned from the parameters passed as part of the generating request.
