URIs and paths are not the same, "http://example.com/somet... and
"http://example.com/someth... are allowed to return different
content. URI.join works off the directory, "/" in your case, rather
than assuming that "/something" is a directory, which may be incorrect.

(My annoyance with this method is that the first argument cannot be a
URI::Generic.)
