* @aURI is a URL to a packaged resource

|
* - format: package_url + PACKAGED_APP_TOKEN + resource_path
|
|
* - example: http://test.com/path/to/package!//resource.html
|
|
* @aCallback is an object implementing nsICacheEntryOpenCallback
|
|
* - this is the target of the async result of the operation
|
|
* - 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)
|
|
*
|
|
* Calling this method will either download the package containing the given
|
|
* resource URI, store it in the cache and pass the cache entry to aCallback,
|
|
* or if that resource has already been downloaded it will be served from
|
|
* the cache.
