Thanks for the pointer, Ilmari! Just checked and it works fine under Windows.

This can also be done using File.split / dirname / basename:

File.dirname "http://foo.com/bar/stuff....
#=> "http://foo.com...

File.basename "http://foo.com/bar/stuff....
#=> "stuff.html"

File.split "http://foo.com/bar/stuff....
#=> ["http://foo.com..., "stuff.html"]

File.join( File.dirname("http://foo.com/bar/doc....),
"relative_link.html" )
# => "http://foo.com/bar/relative_link....

Though that probably breaks on Windows since it has backslashes for
directory separators.
