Hello Folks,

My objective is to stress test a load balanced web server. I wrote a simple script using lwp::simple. The script in its current form is fetching the page. However, since it is initiating the connections seqentially I am actually not stressing the gateway. Could somebody point me in the right direction on how to go about spawning multiple instances. Code snippets would be really really appreciated.

Thanks a lot The current version is pasted below: 
use LWP::Simple;
use strict;
my ($count, $max, $URL);

unless (defined ($URL = shift)) {
    print "\n\nEnter the site address which you would like to access: 
+";
    chomp($URL = <STDIN>);
}
$URL = "http://" . "$URL";
print "Site address is $URL \n";

unless (defined ($max = shift)) {
    print "Enter the number of times to hit the site: ";
    chomp($max = <STDIN>);
}

for ($count = 0; $count <= $max; $count++){
    my $content;
    unless (defined ($content = get $URL)) {
       die "could not get $URL\n";
    }
    if ($content =~ /Test1</font>/i) {
        print ".";
    }
    elsif ($content =~ /Test2</font>/i) { 
        print "Fetched page from Server2 \n";
        $count++;
        &result;
    }
    else { print "Page not retreived \n" }
}

sub result {
    print "page retrieved after $count tries \n";
    exit;
}
