header setting.

        _name is the header field to add.  keyword arguments can be used to
set
        additional parameters for the header field, with underscores
converted
        to dashes.  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.
