Hmm.  Interesting.  I seemed to recall a number of bugs on this issue, 
and it looks like we did use to have them.  The issue was that sites 
actually expected http:/foo and http:foo to be treated as _relative_ 
URIs equivalent to "/foo" and "foo", because that's what some of the 
early URI RFCs defined them to be.

Relevant bug comments are 
https://bugzilla.mozilla.org/show_bug.cgi?id=196088#c11 and 

I just tested, and the above two URIs are handled like http://foo in 
Webkit and Gecko, as relative URIs equivalent to replacing the filename 
by "http:/foo" and "http:foo" in Opera. I can't tell what IE is doing, 
since it loads absolutely nothing when such a URI is clicked over here 
(the document the link is in is at a file:// URI).

Fun times.  ;)
