Hi Jan,
The code that generating the http response(headers + content) does not
have a handle to the HttpServletResponse object. It only has a reference to
the OutputStream.
How about this theory on what's happening - when no headers/status is
committed via the response object, the web container takes it upon itself
to set the headers once it sees the data on the outputstream -
right/wrong ?
Can it(webcontainer-setting-http-response-headers) be suppressed ?
Thanks
Ashish
