* If the user closes the dialog using a cancel button or similar ,
* the callback ' s nsIAuthPromptCallback : : onAuthCancelled method must be

* Calling nsICancelable : : cancel on the returned object SHOULD close the
* dialog and MUST call nsIAuthPromptCallback : : onAuthCancelled on the provided
* callback .
*
* This implementation may :
*
* 1 ) Coalesce identical prompts . This means prompts that are guaranteed to
* want the same auth information from the user . A single prompt will be
* shown ; then the callbacks for all the coalesced prompts will be notified
* with the resulting auth information .
* 2 ) Serialize prompts that are all in the same " context " ( this might mean
* application - wide , for a given window , or something else depending on
* the user interface ) so that the user is not deluged with prompts .
*
* @ throw
* This method may throw any exception when the prompt fails to queue e . g
* because of out - of - memory error . It must not throw when the prompt
* could already be potentially shown to the user . In that case information
* about the failure has to come through the callback . This way we
* prevent multiple dialogs shown to the user because consumer may fall
* back to synchronous prompt on synchronous failure of this method .
