// everyone can change or use this code however and wherever they want ;)

// nb! for posting to microsoft platform webservers you may need to change newlines "/n" to "/r/n"
// microsoft always breaks standards ...

// example how to use:

// following code will post variables "login" and "pass" to server "www.something.com" script "/submit.php"
$reply = post_data ("www.something.com", "/submit.php", array ("login" => $username, "pass" => $password));
