HTTP-sent POST data does not arrive to remote script

[kizokumaru]

I've got some trouble when trying to send a HTTP POST variable to a remote script. I've got this piece of code:

fwrite($this->sock, "POST /" . $this->dest . " HTTP/1.0" . RC);
fwrite($this->sock, "Host: " . $this->IP . RC);
fwrite($this->sock, "Content-type: application/x-www-form-urlencoded" . RC);
fwrite($this->sock, "Authorization: Basic ".base64_encode(USUARIO_AUTHORIZED . ":" . PASSWORD_AUTHORIZED) . RC); fwrite($this->sock, "Content-length: " . strlen($datos) . RC);
fwrite($this->sock, "Accept: /*" . RC);
fwrite($this->sock, RC);
fwrite($this->sock, "$datos" . RC);
fwrite($this->sock, RC);

$this->sock contains a valid sock, RC is a constant containing "\r\n", $this->dest contains the destination PHP script, and $datos = "validation=" . $key;
The fact is that the remote script returns nothing when trying to access $HTTP_POST_VARS['validation'], for example, which makes me think that POST data is not arriving to its destination.
After a few freads and concatenations the remote script returns this:

HTTP/1.1 200 OK Date: Tue, 21 Nov 2006 18:10:31 GMT Server: Apache/2.0.55 (Win32) PHP/5.1.6 X-Powered-By: PHP/5.1.6 Content-Length: 0 Connection: close Content-Type: text/html

Any idea about solving this trouble, or any better method to send the POST data?

Thanks!

I would recommend looking at this page.  It is much easier to post and retrieve data this way than the way you are doing it.
