and a docshell load tye. Unify nsIURILoadCommand and nsIDocShellLoadType enums so they can be treated as the same type. This allows the uriloader to pass the correct load info from the docshell that originates the load over to the docshell that actually ends up loading the url. r=radha, sr=rpotts

/* 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.
