    In essence the xmlhttp = new part creates an empty object that will guide us
    sending a request to the ajax/Tracking.php script that communicates with the database.
    The xmlhttp.onreadystatechange function waits for the php script to finish and then if the
    state of the conversation is OK, reads the reponse from the script. In this small example the
    response will not be any html elements or parts but either "success" or a database error message
    that will get displayed in an alert box.
