Couple of interesting points in your mail, but for the moment I'd like 
to cut to the heart of the matter that's giving me headaches and reply 
only to this part of your mail.

Are you saying that "denote a resource" is the *only* thing that a URI 

Then how can it be that two URIs that denote the *same* resource can 
give me *different* representations when I put them into my browser?

I.e., every time I go to <http://example.org/1434> I see one particular 
page, and every time I go to <http://example.net/~foo/bar> I see another 
particular page, yet the two URIs identify the same resource.

How do you explain this?
