I have two pages: Default.aspx and WebForm1.aspx. One of these pages stores a session variable which works fine until I add code which ads
expiration date to SessionID cookie.
What happens is:
Open default.aspx
Set-Cookie ASP.NET_SessionId=14jhsdfq23jkh13jkh12k1;
expires=Fri, 19-Mar-2010 07:31:47 GMT;
path=/
Click on link to open WebForm1.aspx
No cookies set
Click on link to open Default.aspx (Cookie is reset)
Set-Cookie ASP.NET_SessionId=;
expires=Fri, 19-Mar-2010 07:31:47 GMT;
path=/
So the question would be how should I set SessionID cookie
expiration date correctly?
Default.aspx.cs

using System.Web.UI.WebControls;
namespace WebApplication1
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
lnk.Click += new EventHandler(lnk_Click);
Session["t"] = Guid.NewGuid();
Response.Cookies["ASP.NET_SessionId"].Expires = DateTime.Now.AddDays(2);
}
void lnk_Click(object sender, EventArgs e)
{
Response.Redirect("WebForm1.aspx");
}
}
}
