    HttpCookie myCookie= new HttpCookie(\"myCookie\");
    myCookie.Value = txtC         


        

Answer 1

The default Expires value for a cookie is not a static time, but it creates a Session cookie. This will stay active until the user closes their browser/clears their cookies. You can override this as required.

From the linked page:

Setting the Expires property to MinValue makes this a session Cookie, which is its default value

Answer 2

20 minutes.
In IIS, click on your website, and go to Session State. In the second box (Cookie Settings), you can change the time out(in minutes).
