//these are just in case setting headers forcing it to always expire

error_log(print_r($_POST,TRUE));
if( isset($_POST['query']) && isset($_POST['key']) ){ //checks if the tag post is there and if its been a proper form post
//set content type to CSV (to be set here to be able to access this page also with a browser)
header('Content-type: text/csv');
if($_POST['key']==$SQLKEY){ //validates the SQL key
$query=urldecode($_POST['query']);
if(get_magic_quotes_gpc()){ //check if the worthless pile of crap magic quotes is enabled and if it is, strip the slashes from the query
$query=stripslashes($query);
}
$conn = new mysqli($DB_ADDRESS,$DB_USER,$DB_PASS,$DB_NAME); //connect
if($conn->connect_error){ //checks connection
header("HTTP/1.0 400 Bad Request");
