I'm reading Web Client Programming. I couldnt get the first example in the
book,
connecting to a web server, to work. I finally found something similar that
did work, which was....

sub Connect {
($sockaddr,$there,$response,$tries) = ("Snc4x8");
$there = pack($sockaddr,2,$port, &getaddress($hostname));
$proto = (getprotobyname ('tcp'))[2];
socket(S,AF_INET,SOCK_STREAM,$proto);
connect(S,$there);
}

sub getaddress {
  local($host) = @_;
  local(@ary);
  @ary = gethostbyname($host);
  return(unpack("C4",$ary[4]));
}

sub GetFile {
$file = "/";
select(S);
$|=1;
select(STDOUT);
print S "GET $file\r\n";
@line = <S>;
}

These subroutines will connect to a host and read the home page.
I don't know what the problem could have been with the first example
client in the O'Reilly book.
