public class HttpOutput
extends javax.servlet.ServletOutputStream
implements java.lang.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.

HttpOutput.Interceptor
The HttpOutput.Interceptor is a single intercept point for all
output written to the HttpOutput: via writer; via output stream;
asynchronously; or blocking.

by compressing them.
