* @param aCallback
|

* 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
|
|
*
|
|
* 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.
