File resource is cached

This addon has no special configuration for "cache-control" so the default of 1 day is used... if you want to download a "newer" file with the same name, the old file will be downloaded. This can be avoided with following setting in handleConnectorRequest():

stream.setParameter("Cache-Control", "no-store");
