I want to store the username in the cookie and retrieve it the next time when the user opens the website. Is it possible to create a cookie which doesnt expires when the browser

Answer 1

In addition to what Shai said, if you later want to update the same cookie use:

HttpCookie myCookie = Request.Cookies["MyTestCookie"];
DateTime now = DateTime.Now;

// Set the cookie value.
myCookie.Value = now.ToString();

// Don't forget to reset the Expires property!
myCookie.Expires = now.AddYears(50);
Response.SetCookie(myCookie);

Answer 2

Writing a cookie

HttpCookie myCookie = new HttpCookie("MyTestCookie");
DateTime now = DateTime.Now;

// Set the cookie value.
myCookie.Value = now.ToString();
// Set the cookie expiration date.
myCookie.Expires = now.AddYears(50); // For a cookie to effectively never expire

// Add the cookie.
Response.Cookies.Add(myCookie);

Response.Write("<p> The cookie has been written.");

Reading a cookie

HttpCookie myCookie = Request.Cookies["MyTestCookie"];

// Read the cookie information and display it.
if (myCookie != null)
   Response.Write("<p>"+ myCookie.Name + "<p>"+ myCookie.Value);
else
   Response.Write("not found");
