@NotThreadSafe
public class ContentLengthOutputStream
extends java.io.OutputStream

Output stream that cuts off after a defined number of bytes. This class is used to send content of HTTP messages where the end of the content entity is determined by the value of the Content-Length header. Entities transferred using this stream can be maximum Long.MAX_VALUE long.

Note that this class NEVER closes the underlying stream, even when close gets called. Instead, the stream will be marked as closed and no further output will be permitted.
