<!-- forward액션태그를 이용하고 그 안에서 jsp:param액션태그를 이용하여 파라메터들을 전달하고 있다.
아울러, 페이지 이동에 있어서 내부객체인 request객체는 서로 공유하기 때문에 foward_param_result.jsp
페이지에서는 request를 이용하여 아래의 파라메터값을 참조하면 된다. -->
<jsp:forward page="forward_param_result.jsp">
<jsp:param value="abcde" name="id"/>
<jsp:param value="12345" name="pw"/>
</jsp:forward>
