Do I need to flush the servlet outputstream?

Question

Do I need to \"flush\" the OutputStream from the HttpServletResponse?

I already saw from to Should I close the servlet outputstream? that I don\'t need to close it,

Answer 1

java.lang.Object
  extended byjava.io.Writer
      extended byjavax.servlet.jsp.JspWriter


close
public abstract void close()
                    throws IOException
Close the stream, flushing it first. 
This method needs not be invoked explicitly for the initial JspWriter as the code generated by the JSP container will automatically include a call to close(). 

Closing a previously-closed stream, unlike flush(), has no effect. 


Throws: 
IOException - If an I/O error occurs

============================

So, DO NOT close the output stream explicitly.
