    <c:set value="10000" var="maxUser" scope="application"/>
    <c:set value="20" var="maxIdelTime" scope="session"/>
    <c:set value="hellking" var="accountId" scope="request"/>
    <c:set value="next.jsp" var="nextPage" scope="page"/>
    在没有调用c:remove之前,有这些参数;
    maxUser=<c:out value="${maxUser }"/>
    maxIdelTime=<c:out value="${maxIdelTime }"/>
    accountId=<c:out value="${accountId }"/>
    nextPage=<c:out value="${nextPage }"/>
    <hr/>调用c:remove...
    <c:remove var="maxUser" scope="application"/>
    <c:remove var="maxIdelTime" scope="session"/>
    <c:remove var="accountId" scope="request"/>
    <c:remove var="nextPage" scope="page"/>
    调用了c:remove之后,这些参数值为:
    maxUser=<c:out value="${maxUser}"></c:out>
    maxIdelTime=<c:out value="${maxIdelTime }"></c:out>
    accountId=<c:out value="${accountId }"></c:out>
    nextPage=<c:out value="${nextPage }"/>
</body>
</html>
<c:set>设置变量属性的值;
<c:out>输出属性的值;
<c:remvoe>删除前面设置的属性;
