Discussion

In this example, the custom class, ImageCacheManager, checks whether the requested image is cached locally first, before trying to load it from the Internet. If the local version exists, it is used. If not, the remote version is loaded and cached. This class is a singleton, and the single instance of this class can be retrieved by calling the getInstance method.

Note

The application uses the as3corelib library for the MD5 hashing. You must add this library to your project for it to work. You can download the application here: http://code.google.com/p/as3corelib/.
