On a related noted (related by code, not by problem): Using HTTP/1.0 will prevent your code from working against a virtually hosted site. (Virtual hosting allows multiple domains to share an IP address. Making that work requires passing a domain name in the HTTP request.) Switching to HTTP/1.1 should be very, very easy. Try changing 
      print $sock "GET $url HTTP/1.0
  Host: localhost

[download]
to 
      print $sock "GET $url HTTP/1.1
  Host: $host

[download]
That should do it.
