close (NetStream.setBufferTime) method
public close() : Void
Stops playing all data on the stream, sets the NetStream.time property to 0, and makes the stream available for another use. This command also deletes the local copy of an FLV file that was downloaded using HTTP. Although Flash Player deletes the local copy of the FLV file that it creates, a copy of the video may persist in the browser's cache directory. If complete prevention of caching or local storage of the FLV file is required, use Flash Media Server.
ActionScript 1.0; Flash Player 7
NOTE: This method is also supported in Flash Player 6 when used with Flash Media Server. For more information, see the Flash Media Server documentation.
The following close() function closes a connection and deletes the temporary copy of video1.flv that was stored on the local disk when you click the button called close_btn:
var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);
my_video.attachVideo(stream_ns);
stream_ns.play("video1.flv");
close_btn.onRelease = function(){
stream_ns.close();
};
