Forms may be submitted via two possible HTTP methods: get and post. These methods determine whether the form element data is sent to the server appended to the action attribute URL (get) or as a transaction message body (post). In practice, when the action and method attributes are not assigned in a form element, the form performs an unconditional reload of the same document, restoring form controls to their default values. Note that the method property is read-only in Internet Explorer 3.
