Hmm. Or you can better do it this way:
You can have script1 generate HTML containing a form (POST HTTP-method) with all your items specified by hidden fields, i.e. generate something like
<form action="script2.cgi" method="post">
<!-- Hidden fields -->
<input type="hidden" name="item0" value="value0">
<input type="hidden" name="item1" value="value1">
<!-- hidden fields end here-->
<input type="submit" value="submit">
</form>
When the visitor hits the submit button, the hidden fields are sent and by reading the form you can parse and get the (item0, value0), (item1, value1) pairs.
If you insist on a hyperlink, then the only method you can pass the info to script2 is by HTTP GET, i.e. on the URL as params. Script1 generates HTML containing a link with href "script2.cgi?item0&item1&..."
Your script then parses the env. variable $ENV{'QUERY_STRING'} and gets all key-value pairs to form the array again.
You will first need to convert the special characters in the array items (say @) into the % form (i.e. %40) in order to form a valid URL.
All such item mangling should be easy if you use CGI.pm.
Of course I prefer the POST method, as the URL is less noisy, and this is the method I use, right now.

cgi::compile
CGI::Compile(3pm) User Contributed Perl Documentation CGI::Compile(3pm)
NAME
CGI::Compile - Compile .cgi scripts to a code reference like ModPerl::Registry
SYNOPSIS
use CGI::Compile;
my $sub = CGI::Compile->compile("/path/to/script.cgi");
DESCRIPTION
CGI::Compile is an utility to compile CGI scripts into a code reference that can run many times on its own namespace, as long as the script
is ready to run on a persistent environment.
NOTE: for best results, load CGI::Compile before any modules used by your CGIs.
RUN ON PSGI
Combined with CGI::Emulate::PSGI, your CGI script can be turned into a persistent PSGI application like:
use CGI::Emulate::PSGI;
use CGI::Compile;
my $cgi_script = "/path/to/foo.cgi";
my $sub = CGI::Compile->compile($cgi_script);
my $app = CGI::Emulate::PSGI->handler($sub);
# $app is a PSGI application
CAVEATS
If your CGI script has a subroutine that references the lexical scope variable outside the subroutine, you'll see warnings such as:
Variable "$q" is not available at ...
Variable "$counter" will not stay shared at ...
This is due to the way this module compiles the whole script into a big "sub". To solve this, you have to update your code to pass around
the lexical variables, or replace "my" with "our". See also <http://perl.apache.org/docs/1.0/guide/porting.html#The_First_Mystery> for more
details.
