Normally the parameter will be added as key="value" unless value is None, in which case only the key will be added. Example: h.add_header('content-disposition', 'attachment', filename='bud.gif') Note that unlike the corresponding 'email.message' method, this does *not* handle '(charset, language, value)' tuples: all values must be strings or None.
