Yes.
When output is first sent on a servlet's Writer or OutputStream the
servlet engine will send the compute and output the response header
before any actual output.
Any session sent in a cookie will have to be set in that response
header.
So the session must be setup before the response header is written.
Curiously this would not be required using session re-writing, since
nothing gets set in the header.
Hope that explains it.
