I read Lincoln Stein's excellent book on CGI.pm (the module he wrote). After reading the book I still had a hard time writing a cookie. For some reason the perl'ish way to set a cookie didn't work. In fact I see questions from people having the exact same problem.. so .. here's my solution (very short and simple)
#!/usr/bin/perl -w

use CGI qw/:standard/; 

$the_cookie = cookie( -name=>'ident', 
-value=>somevalue); 

print "Set-Cookie: $the_cookie\n"; 

# NOTE: you cannot set the cookie and define it all on one line
# you MUST create the cookie first .. then set it with a print stateme
