AFAICT the HttpServletResponse object a Filter sees doesn't contain the Dat=
e=20
and Server header fields. These seem to be added later in the response chai=
n.=20
I therefore doubt a filter will help you. Maybe a valve will get the task=20
done, but since I've never worked with a homegrown Valve, I don't know.
