The problem is not using forward and include on the same page. The problem
is the way forward works.
The logic of forward is '"I'm done processing, and I haven't written any
ouput back to the client, let somebody else do that"
This means you cannot forward AFTER you've written anything the the ouput
stream. Your include does a flush=true (it has to in the current spec.).
What you really want to do here (I would guess), is a
<%@ include file="header.html" %>, i.e. a static include not a dynamic
include,
