Passing a hash to a cgi outside a form?

[perl <pe...@wcn.co.uk>]

Hi there!

Sorry for this question which might sound easy to you, but, does anyone know :
How can a CGI pass and receive a hash without a form?

Please have a look at the following simple scripts :

This is test.cgi
-----------------------
#!/usr/bin/perl
use CGI;

$list->{'value1'} = 'apple';
$list->{'value2'} = 'fruit';

print "Location: test2.cgi?list=$list \n\n";
----------------------

This is test2.cgi
----------------------
#!/usr/bin/perl

use CGI qw (:standard);

print header;

$list = param('list');

foreach (keys %{$list})
{
        print "KEY IN LIST = ",$_,br;
}

----------------------

Thank you for your help !

Passing a Hash is a CGI proble (and done like all hash passing). 
Mod_perl is not CGI.

Please - if you can. try to send messages as text only without an
attachment.

You might also try Data::Dumper to create eval-able expressions -> hashes,
arrays, and other complex objects.

you can't do this, dude. test.cgi dies and so do all it's pointers to
structures in memory.

try looking at Apache::Registry or mod_perl with the Apache::Filter
mod.

Or if you want to keep these things as cgi's look at LWP which lets you
make http requests from within perl programs. 

However, I would probably just make some subroutines that both cgis could
use via require or use. the memory structures still are destroyed when the
cgi dies.

 It really depends if your intent is to reuse code or pass a
structure that is already in memory. if it is the former, look at LWP or
the subroutine example. if it is the former, checkout the mod_perl and
Filter stuff.

hope this helps,
