If you are trying to count unique URLs for each $counter, try: 
 $hash{$counter}{url}{$CurrentURL}++; # Auto-vivify and count

    The syntax of pushing the value onto the hash key did the trick. I used data::Dumper and here is a sample of a record: 
    '46' => {
          'doc' => 'J 29.9/6:',
           'url' => [
                               'http://www.myurl.com',
                               'http://www.mysecondurl.com'
                             ],
                    'item' => {
                                '2' => undef
                              },
                    'title' => 'Sourcebook of criminal justice statist
+ics'
                  },
