http://perlmonks.com/index.pl?node_id=68135
        looks like the file name is: index.pl?node_id=68135
               and the extension is: pl?node_id=68135
   We even got a query string, whoa: node_id=68135
      so the true filename would be: index.pl?
and the true file extension would b: pl

http://www.foobar.com/foo/
        looks like the file name is: 
               and the extension is: com/foo/

http://www.foobar.com/foo?test
        looks like the file name is: foo?test
               and the extension is: com/foo?test
   We even got a query string, whoa: test
      so the true filename would be: foo?
and the true file extension would b: com/foo

http:///file.ext
        looks like the file name is: file.ext
               and the extension is: ext
