public class HttpOutput extends ServletOutputStream implements Runnable
HttpOutput
implements ServletOutputStream
as required by the Servlet specification.
HttpOutput
buffers content written by the application until a
further write will overflow the buffer, at which point it triggers a commit
of the response.
HttpOutput
can be closed and reopened, to allow requests included
via RequestDispatcher.include(ServletRequest, ServletResponse)
to
close the stream, to be reopened after the inclusion ends.
