* The uri dispatcher is responsible for taking uri's, determining

|
* the content and routing the opened url to the correct content
|
|
* handler.
|
|
*
|
|
* When you encounter a url you want to open, you typically call
|
|
* openURI, passing it the content listener for the window the uri is
|
|
* originating from. The uri dispatcher opens the url to discover the
|
|
* content type. It then gives the content listener first crack at
|
|
* handling the content. If it doesn't want it, the dispatcher tries
|
|
* to hand it off one of the registered content listeners. This allows
|
|
* running applications the chance to jump in and handle the content.
|
|
*
|
|
* If that also fails, then the uri dispatcher goes to the registry
|
|
* looking for the preferred content handler for the content type
|
|
* of the uri. The content handler may create an app instance
|
|
* or it may hand the contents off to a platform specific plugin
|
|
* or helper app. Or it may hand the url off to an OS registered
|
|
* application.
