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 ] );

Hi all,

If I'm sending single valued data over web, eg. a=111, b=222, c=333,
then I can do
    http://.../xxx.cgi?a=111&b=222&c=333

How do I send array data, like A[1]=111, A[2]=222, A[3]=333 to a CGI
script?  I don't think I can do something like
    http://.../xxx.cgi?A[1]=111&A[2]=222&A[3]=333
Or, can I?

I have seen a same variable repeated,
    http://.../xxx.cgi?A=111&A=222&A=333
but that means the CGI script has to build the array.
