冉冉升起的如银的炊烟，那更古沉默永不停息的小溪，那驮着夕阳缓缓独行的老牛，一方方秧田像棋盘格子，绿绒绒的秧苗，织成一幅幅地毯，远远地伸向天际；丛丛绿树掩映着青砖红瓦的房屋。春天，故乡的松树林依然郁郁苍苍，映山红却已开遍山丘。

${pageContext.request} |取得请求对象<br>
${pageContext.session} |取得session对象<br>
${pageContext.request.queryString} |取得请求的参数字符串<br>
${pageContext.request.requestURL} |取得请求的URL，但不包括请求之参数字符串<br>
${pageContext.request.contextPath} |服务的web application的名称<br>
${pageContext.request.method} |取得HTTP的方法(GET、POST)<br>
${pageContext.request.protocol} |取得使用的协议(HTTP/1.1、HTTP/1.0)<br>
${pageContext.request.remoteUser} |取得用户名称<br>
${pageContext.session.new} |判断session是否为新的，所谓新的session，表示刚由server产生而client尚未使用<br>
${pageContext.session.id} |取得session的ID<br> ${header["User-Agent"]}|用户浏览器的版本<br/>
${header["Host"]}|IP<br/>
${pageContext.request.remoteAddr } |取得用户的IP地址<br>
${pageContext.servletContext.serverInfo}|取得主机端的服务信息<br>
${pageContext.request.serverPort}|端口信息<br>
${pageContext.request.serverName}|服务器名称<br>
${pageContext.request.remoteHost}|客户机名称<br>
