ZATS Download

In a ZK application, developers usually perform a download through the Filedownload when some events occurred..

The following is a typical example about downloading a file:

<zk>
	<button id="btn" label="download">
		<attribute name="onClick"><![CDATA[
			org.zkoss.zul.Filedownload.save("foo.txt", "application/octet-stream");
		]]>
		</attribute>
	</button>
</zk>

Actually, the download mechanism is a two steps process. When you invoke save method, the Filedownload simply notifies ZK client engine of the download URL. Then, the client engine download such file according to the received URL.
