public class ZipResourceStream
An IResourceStream that ZIPs a directory's contents on the fly
NOTE 1. As a future improvement, cache a map of generated ZIP files for every directory and use a Watcher to detect modifications in this directory. Using ehcache would be good for that, but it's not in Wicket dependencies yet. No caching of the generated ZIP files is done yet.
NOTE 2. As a future improvement, implement getLastModified() and request ResourceStreamRequestTarget to generate Last-Modified and Expires HTTP headers. No HTTP cache headers are provided yet. See WICKET-385
