this works and you see the page 'filling up", it seams the Reponse object does not recognise the setting of Buffer to true until it has flushed the response automatically, I just pushed 300 spaces onto the stream as a test and it works.

            private void Button1_Click(object sender, System.EventArgs e)
            {
                  Response.Buffer= true;

//                  Response.Write( "0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789<br>" );
                  Response.Write( "                                                                                                        " );
                  Response.Write( "                                                                                                        " );
                  Response.Write( "                                                                                                        " );

                  Response.Flush();


                  Response.Write("test2");
                  for( int i = 0  ; i < 100 ; i ++ )
                  {
                        
                        Response.Write( string.Format("Message {0}<br>" , i ) ) ;
                        Response.Flush();
                        System.Threading.Thread.Sleep(100);
                  }
            }
