* - aCallback->OnCacheEntryCheck() is called to verify the entry is valid
* - aCallback->OnCacheEntryAvailable() is called with a pointer to the
* the cached entry, if one exists, or an error code otherwise
* - aCallback is kept alive using an nsCOMPtr until OnCacheEntryAvailable
* is called
* @aInfo is an object used to determine the cache jar this resource goes in.
* - usually created by calling GetLoadContextInfo(requestingChannel)
* @param aPrincipal
* the principal associated to the URL of a packaged resource
* URL format: package_url + PACKAGED_APP_TOKEN + resource_path
* example: http://test.com/path/to/package!//resource.html
* @param aFlags
