CGI passing arrays/hashes to another CGI script

If I have a Perl CGI script (script01), which fills an array(s) with information and outputs a HTML page with a link to another CGI page (script02); is there anyway to pass the array(s) from "script01" to "script02" when the page visitor clicks the link? Hope that makes sense! :)

NAME

       Plack::App::CGIBin - cgi-bin replacement for Plack servers

SYNOPSIS

	 use Plack::App::CGIBin;
	 use Plack::Builder;

	 my $app = Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app;
	 builder {
	     mount "/cgi-bin" => $app;
	 };

	 # Or from the command line
	 plackup -MPlack::App::CGIBin -e 'Plack::App::CGIBin->new(root => "/path/to/cgi-bin")->to_app'

DESCRIPTION

       Plack::App::CGIBin allows you to load CGI scripts from a directory and convert them into a PSGI application.

       This would give you the extreme easiness when you have bunch of old CGI scripts that is loaded using cgi-bin of Apache web server.

HOW IT WORKS

       This application checks if a given file path is a perl script and if so, uses CGI::Compile to compile a CGI script into a sub (like
       ModPerl::Registry) and then run it as a persistent application using CGI::Emulate::PSGI.

       If the given file is not a perl script, it executes the script just like a normal CGI script with fork & exec. This is like a normal web
       server mode and no performance benefit is achieved.

       The default mechanism to determine if a given file is a Perl script is as follows:

       o   Check if the filename ends with ".pl". If yes, it is a Perl script.

       o   Open the file and see if the shebang (first line of the file) contains the word "perl" (like "#!/usr/bin/perl"). If yes, it is a Perl
	   script.

       You can customize this behavior by passing "exec_cb" callback, which takes a file path to its first argument.

       For example, if your perl-based CGI script uses lots of global variables and such and are not ready to run on a persistent environment, you
       can do:

	 my $app = Plack::App::CGIBin->new(
	     root => "/path/to/cgi-bin",
	     exec_cb => sub { 1 },
	 )->to_app;

       to always force the execute option for any files.

       See also Plack::App::WrapCGI if you compile one CGI script into a PSGI application without serving CGI scripts from a directory, to remove
       overhead of filesystem lookups, etc.
