[GTALUG] Sending array variable over CGI ?

[Alex Beamish]

Sure, the second way you listed is correct, and the CGI would store each
value for that key into an array.

In that example, you would end up with a Hash of Arrays. In Perl, that
would look like this:

  %params = ( 'A' => [ 111, 222, 333 ] );
