remember me cookie in asp .net

hi,
I'm trying to remember a user who has visited the page. what i found out was
to use persistent cookie, is there any other way that i can remember the
user next time he visit?

When using cookies, I used the code below to add
-----in login.aspx------
Dim aCookie As New HttpCookie("userInfo")
aCookie.Values("userID") = "1"
aCookie.Expires = DateTime.Now.AddYears(50)
Response.Cookies.Add(aCookie)

and to retrieve, I used
-----in default.aspx------
Server.HtmlEncode(Request.Cookies("userInfo")("userId"))

but I wasn't able to retrieve values from the cookies. does it matter where
I create the cookies, as i check for the cookie in default.aspx and redirect
to login.aspx if the cookie is not found.

Hope someone can help!

Thank You!!!

Hi James,

One possible reason you can't retrieve cookie is that your browser blocks
cookie. Hence it never writes cookie to client computer.

James,
Here is some very simple cookie code as an example:

private void Page_Load(object sender, System.EventArgs e)
{
    if(Request.Cookies["test"]==null)
        {
        HttpCookie c = new HttpCookie("test","hello") ;
            c.Expires=new DateTime(2007,1,1);
            Response.Cookies.Add(c);
        }
    Response.Write(Request.Cookies["test"].Value);
//....

IE Cookie Viewer is a good tool to find and use when debugging cookies. So
is any recent releases of Firefox or Netscape.

Hi,

Thanks for your replies!
I did a check, had my browser to allowed cookies, the cookie was created
thou, but using IE Cookie Viewer recommended by Clinton, the value UserID =
1 was stored when I first access my page, but when I access it the second
time, the cookie exists but the value disappeared!

Is there other possibilities, or any mistake that I could have made?

Thank you! Hope to hear from you soon!
