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!

appconfig::cgi
AppConfig::CGI(3) User Contributed Perl Documentation AppConfig::CGI(3)
NAME
AppConfig::CGI - Perl5 module for processing CGI script parameters.
SYNOPSIS
use AppConfig::CGI;
my $state = AppConfig::State->new(\%cfg);
my $cgi = AppConfig::CGI->new($state);
$cgi->parse($cgi_query);
$cgi->parse(); # looks for CGI query in environment
OVERVIEW
AppConfig::CGI is a Perl5 module which implements a CGI interface to AppConfig. It examines the QUERY_STRING environment variable, or a
string passed explicitly by parameter, which represents the additional parameters passed to a CGI query. This is then used to update
variable values in an AppConfig::State object accordingly.
AppConfig::CGI is distributed as part of the AppConfig bundle.
DESCRIPTION
USING THE AppConfig::CGI MODULE
To import and use the AppConfig::CGI module the following line should appear in your Perl script:
use AppConfig::CGI;
AppConfig::CGI is used automatically if you use the AppConfig module and create an AppConfig::CGI object through the cgi() method.
AppConfig::CGI is implemented using object-oriented methods. A new AppConfig::CGI object is created and initialised using the new()
method. This returns a reference to a new AppConfig::CGI object. A reference to an AppConfig::State object should be passed in as the
first parameter:
my $state = AppConfig::State->new();
my $cgi = AppConfig::CGI->new($state);
This will create and return a reference to a new AppConfig::CGI object.
PARSING CGI QUERIES
The "parse()" method is used to parse a CGI query which can be specified explicitly, or is automatically extracted from the "QUERY_STRING"
CGI environment variable. This currently limits the module to only supporting the GET method.
See AppConfig for information about using the AppConfig::CGI module via the cgi() method.
