Assuming the remote server is using cookies rather than session IDs (you can find out by closing your browser and then trying to reconnect without logging in: if you can, then it's cookies; otherwise, it's sessions), you need to not only specify the cookie_jar that you're using but to also load it. I find that setting the cookie_jar and "autosave" in the call to 'new()' causes W::M to spit out errors - so I tend to do it manually. Sample script follows: 

#!/usr/bin/perl -w
use strict;
use WWW::Mechanize;

my $cookie_file = "/tmp/cookies";
my $agent = WWW::Mechanize->new();

if (! -s $cookie_file){
    $agent->get("http://okopnik.com/PHP/other/cookies.php");
    # Save the cookie from this session
    $agent->cookie_jar->save($cookie_file);
}
else {
    $agent->cookie_jar->load($cookie_file);
    $agent->get("http://okopnik.com/PHP/other/cookies.php");
}

print $agent->content;

Assuming that you start with an empty "/tmp/cookies", this will populate it with a cookie the first time you run it (and show you a silly message that indicates that); subsequent runs will show that the cookie has been set and is active. Do note that the above PHP script has a fairly short cookie lifetime (2 minutes, if I recall correctly.)
