Well, it needs to be both updated and fixed...:

"Note also that the HTTP Etag can be shared by identical resources that 
have different URIs. For example, if http://mirror1.example.org/foo and 
http://mirror2.example.org/foo share the same ETags, you can then deduct 
that those are equivalent resources."

This is incorrect.

Besides that, it may have some overlap with the much quoted "Cool URIs 
don't change"; so maybe this should be consolidated into a single
