in reply to Perl - get HTTP streaming server data

If your server is serving HTTP then you almost certainly don't want to use raw sockets to talk to it. Take a look at LWP. Your code might be a simple as:

use LWP::Simple;

if (head($host)) {
  # $host returned data
} else {
  # $host didn't return data
}
