Cookies problem in ASP.net

I am currently working on an ASP.net c# web application. I am trying to use a cookie which will store the users id number from the database.

I set the cookie when the user logs in using the following code:

Response.Cookies["userID"].Value = reader.GetString("use_id");

When the user logs in it does a Response.Redirect to /software/index.aspx.

This file then retrieves the value of the cookie with the following code

HttpContext.Current.Request.Cookies["userID"].Value

When开发者_如何学C I then click a link to a different page e.g. ../accounts/index.aspx and I try to run the same code to get the value of the cookie, the value is empty.

What am I doing wrong.

Thanks for any help you can provide.

Try using the Add method on the cookies collection and see if it makes a difference:

Response.Cookies.Add(new HttpCookie("userID")
        {
            Expires = DateTime.Now.AddDays(1),
            Value = reader.GetString("use_id"),
            HttpOnly = true
        });

Edit: Typos.

Have you set an expiry time on the cookie?

Is the index.aspx a page on the same site that gave you the cookie?
