<Content>session.setMaxInactiveInterval(-1);不过期。
但是我实用下来好像还是会过期的，不过时间比较长，用户如果这么长时间不动网页的话，很有可能是离开了，这样过期反而是好事，安全</Content>

<Content>Cookie cookies[]=request.getCookies();
//取出cookies值，并放到数组cookies里
   int j = (cookies==null )?0:cookies.length ;
//着句我就不明白了
   for ( int i = 0 ; i < j ;i++ )
   {
     if ( cookies[i].getName().equals("USERNAME") ) 
        userName = cookies[i].getValue();
     else if ( cookies[i].getName().equals("TIMEZONE") ) 
        timeZone = cookies[i].getValue();
//根据cookie的名字在数组中查找其数值.还有那个else是干什么的？
   }
下面是我自己写的一段放在另一个页面。如果不登陆直接访问就会出错！
再次刷新就会显示，可是显示结果总一些乱七八糟的数据。奇怪的是if(myCookie.length > 0)没起作用！
<%
Cookie myCookie[]=request.getCookies();//本人认为可能是着句出的问题
if(myCookie.length > 0){
	for (int i =0; i < myCookie.length; i++){
Cookie newCookie= myCookie[i];
//username = newCookie.getValue();
out.print(newCookie.getName());
out.print(newCookie.getValue());
	}
	}
