HTP Response does not respond correctly to flush()

           Summary: HTP Response does not respond correctly to flush()
           Product: Tomcat 4
           Version: 4.1.12
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Connector:Coyote HTTP/1.1
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: jpettens@rochester.rr.com


The code below processes a servlet response.  In TC4.0.6 the client does
get the response message at the flush().  The sleep does not effect 
the delivery.

In TC 4.1.12, the output does not get delivered until after the code gets back
into the area around:

org.apache.coyote.tomcat4.CoyoteAdapter.service(org.apache.coyote.Request,
org.apache.coyote.Response) line: 226

Bottom line is the flush() has no effect on getting the data out of the stream.

My normal client is java code, however, I have reproduced the problem 
using this code chunk using either mozilla or IE6 in place of the clients.


        try {
            logger.debug( "Release requestor" );
            response.setContentType( "text/plain; charset=ISO-8859-1" );

            PrintWriter out = response.getWriter();
            out.println( "OK" );
            out.flush();
            out.close();   // client should get "OK" message at this time
            logger.debug( "Release requestor - done" );
            String   readQueue = request.getParameter( "readQueue" );
            logger.debug( "Sleeping" );
           Thread.sleep(6000);
           logger.debug( "awake" );

            // Pull off parms passed and exec ReadCntl
        } catch ( Exception e ) {
            logger.error("Unexpected error", e);
        }
