I know the annotation server did not know
that http://www.w3.org/2001/Annotea
 and http://www.w3.org/2001/Annotea/
 and http://www.w3.org/2001/Annotea/Overview
 and http://www.w3.org/2001/Annotea/index
 and http://www.w3.org/2001/Annotea/Overview.html
 and http://www.w3.org/2001/Annotea/index.html
might be the same on some sites. The annotation server has no
efficient way of knowing this. The client could GET /2001/Annotea
and get a redirect so it knows not to make annotations for
/2001/Annotea. Ideally GET /2001/Annotea/ would get a Location:
http://www.w3.org/2001/Annotea/Overview.html header and then the
client could know what location to annotate. The www.w3.org apache
doesn't currently supply this Location header. I'll probably fix
that this summer. It will be interesting to see how we can get to
this info in mozilla.
