Hi, I think you miss accept type in the code. here I attached correct code for your help. 
use strict;
use HTTP::Cookies;
use LWP::UserAgent;
my $ua = LWP::UserAgent->new(show_progress=>1);
$ua->agent("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:26.0) Gecko/2010010
+1 Firefox/26.0");
$ua->timeout(30);
$ua->cookie_jar({});
my $filename ="indiegogo";
my $cookie_file = $filename."_cookie.txt";
unlink($cookie_file);
my $cookie = HTTP::Cookies->new(file=>$cookie_file,autosave=>1);
$ua->cookie_jar($cookie);
my $url = 'http://www.digikey.com/product-search/en?KeyWords=C0603C474
+K4PACTU&WT.z_header=search_go';
my $req = HTTP::Request->new(GET=>$url); 
$req->header("Accept"=>"text/html,application/xhtml+xml,application/xm
+l;q=0.9,*/*;q=0.8"); 
$req->header("Content-Type"=>"application/x-www-form-urlencoded"); 
my $res = $ua->request($req); 
$cookie->extract_cookies($res); 
$cookie->save; 
$cookie->add_cookie_header($req); 
my $code = $res->code(); 
print $code,"\n"; 
if($code =~ m/50/is) 
{ 
    sleep 1000; 
    goto REPEAT; 
}
my $content = $res->content();
open sr,">digikey.html";
print sr $content;
close sr;
