IMHO it is not a good idea to use a File method for URL's because 
File.basename has different criteria

irb(main):003:0> File.basename 'http://test.com/aaa\\bbb.txt'
=> "bbb.txt"

Although I am not sure whether a backslash is allowed there, this is 
what I'd do:

irb(main):001:0> url = 'http://www.example.com/x/y/z/myfile.txt'
=> "http://www.example.com/x/y/z/myfile.txt"
irb(main):002:0> name = url[%r{[^/]+\z}]
=> "myfile.txt"

Kind regards
