in reply to Perl CGI multithreading

Hi
When using threads, I think we should consider three stages.. 1. create 2. Join 3. detach

create - Creating a new thread
join - Get the values from a already running thread
detach - kill or terminate a running thread


You may refer this tutorial before digging your program..i am going to read first... :)
The following code is working for me.
#!/usr/bin/perl

use CGI;
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);
use strict;
use warnings;
use threads;
my $cgi = new CGI;
print $cgi->header();
print <<"endhere";

<html>

<head>
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="Content-Type" content="text/html; charset=windows-12
+52">
</head>

<body>
endhere

my $n=threads->create(\&new1);
my $m=threads->create(\&new2);
sleep(1);
my @data1 = $n->join;
print @data1 . "\n";
my @data2 = $m->join;
print @data2 . "\n";
#$n->detach;
#$m->detach;
sub new1
{
   my $i=0;
   while(1)
   {
        print "IIIII $i <br>\n";
        $i++;
        last if($i==25);
        sleep(1);

   }
}

sub new2
{
   my $i=0;
   while(1)
   {
        print "JJJJJ $i <br>\n";
        $i++;
        last if($i==25);
        sleep(1);

   }
}
print <<"endhere";
</body>
</html>
endhere
