Disable Transfer-Encoding chunked from StreamResponse

Hi,

I have a problem with Transfer-Encoding chunked on an kml/xml file. I
need to disable it to use the full response as one element for
OpenLayers javascript framework.

How can I disable Transfer-Encoding chunked ? I tried to do this in
the StreamResponse :

    @Override
    public void prepareResponse(Response response) {
        response.setHeader("Transfer-Encoding", null);
    }

but the Transfer-Encoding still appears in firebug...

Server	Apache-Coyote/1.1
Content-Type	application/vnd.google-earth.kml+xml
Transfer-Encoding	chunked
Date	Thu, 08 Jul 2010 11:32:07 GMT

Damn'it, thx Thiago...

A configuration may be exists in web.xml, but I find nowhere how to do
it...

Thanks for the info! It's a good ideea to set the content length header if  
you already know it, anyway. :)

I resolve my problem setting the Content-Length of the result Stream : 

    @Override
    public void prepareResponse(Response response) {
        response.setHeader("Content-Length", "" + length);
    }

where length = inputStream.available(); or file.length();

The Transfer-Encoding is not used anymore if Content-Length is
defined :)

I really don't know the answer, but I guess this is related to the server  
configuration, not Tapestry-related.
