Woa.  Stop. No.   You can't access < http://www.example.com/ 
mophor#me> as it isn't a web page.
The function 'access web page' takes a URI with no hash.

The fact that the id http://www.example.com/mophor#me is used at all  
indicates that  "http://www.example.com/mophor" identifies a  
document, before you even think of access it.
Because the "foo#bar" means   "the thing identified by the local id  
bar within foo" in the web architecture.

You can look up < http://www.example.com/mophor#me> which means, on  
the CLIENT, stripping off the "#me"
