Http request for php page

Question

I have this code to call a php page from Indesign:
reply = "";
conn = new Socket;
if (conn.open ("www.terazo.be:80")) {
     conn.write ("GET /ipadres.php HTTP/1.0\n\n");
     // and read the server's reply
     reply = conn.read(999999);
     conn.close();
alert(reply);
I get a 404 response (not found).
But I am sure this file (ipadres.php) exists on the server.
Any suggestions?
Thanks,
Michel

This is just like Roy Marshall's problem in http://forums.adobe.com/message/3964080#3964080.
Your server requires HTTP/1.1 for the query, meaning you must specify the Host: header. See the example there; or on the command line:
$ telnet www.terazo.be 80
Trying 188.93.150.25...
Connected to www.terazo.be.
Escape character is '^]'.
GET /ipadres.php HTTP/1.1
Host: www.terazo.be
HTTP/1.1 200 OK

Note that the answer it gives is certainly not the  IPv4 address of your client on the global Internet.
