i have a test like this :
cookie.jsp:
<html>
<head>
</head>
<body>
<%
String cookieName="SNS";
Cookie cookie=new Cookie(cookieName, "maxAgeTest");
cookie.setMaxAge(60*60);
response.addCookie(cookie);
%>
</body>
</html>
and read.jsp is :
<html>
<head>
</head>
<body>
<table border=1>
<tr><td>Name</td><td>value</td></tr>
<%
Cookie cookies[]=request.getCookies();
Cookie sCookie=null;
String svalue=null;
String sname=null;
int sage ;
for(int i=0;i<cookies.length;i++)
{
sCookie=cookies[i];
svalue=sCookie.getValue();
sname=sCookie.getName();
sage=sCookie.getMaxAge();
%>
<tr><td><%=sname%></td><td><%=svalue%></td><td><%=sage%></td></tr>
<%
}
%>
</table>
</body>
</html>
but the result is :
Name value maxAge
JSESSIONID DB3561A47B37FCA8CA25EA04B80A26C7 -1
SNS maxAgeTest -1
