Re: HTTP Manipulation

[cdowns <cdowns () drippingdead com>]

Jeremy,
  
One way is to match what you are looking for.... Like so...

  while($response = <$sock>) {
        chomp($response);
        if($response =~ /\d$/) {
            print "$response\n";
            return($response);
        }
   }
   close($sock);
}


Hope this helps.
