Subject: outputstream.flush() hangs at 32K

>I have a servlet on TC 5.5.9 that services a page with applet content that 
>will reguire three GETs to complete the page 1) basic page, 2) applet jar 
>and 3)image.  The basic page GETs served OK and the browser comes back with 
>a GET to request the JAR file which is modestly large (150K) so I attempt

>ByteArrayOutputStream to get the real byte count as usual, then setup the 
>headers before starting the write, then loop on [write a chunk, flush 
>chunk], but the flush hangs at the 32K mark every time (actually, the next 
>flush after the previous 32k mark was hit).  I've set the response buffer 
>size to be larger than the byte array but it still does not help.  I know
