That can't be what's happening; *without* my module, the request is
served with *no* last-modified header and *no* etag header -- because
it's a document parsed for SSI, and the default handler therefore
doesn't provide those things.
*With* my module, it's served with the last-modified date specified in
my handler -- *not* the date on the file, for example; and it changes
if I change what my module does -- and with an ETAG value that it gets
from somewhere.

This makes no difference, and I can't find any documentation anywhere

Thanks very much, will investigate these.
