You can extend the life of a cookie beyond the current browser session by setting an expiration date and saving the expiry date within the cookie. This can be done by setting the 'expires' attribute to a date and time.
Using cookies to do stuff Cookies without an Expires or Max-Age attribute are treated as session cookies, which means they are removed once the browser is closed. Setting a value on either Expires or Max-Age makes them permanent cookies, since they will exist until they hit their expiry date.
If we does not set the expiry time of a cookie then when it will delete its self. The default Expiration Period for a Session is 20 minutes. The default Expiration Period for a Cookie is 30 minutes.
The Kind property of Expires is used to determine if the cookie is set to DateTimeKind.
I'm setting a new cookie
func f1(w http.ResponseWriter, r *http.Request) {
...
expire := time.Now().AddDate(0, 1, 0)
cookie := http.Cookie{"token", token, "/", "domain", expire, expire.Format(time.UnixDate), 86400, true, true, "token=" + token, []string{"token=" + token}}
http.SetCookie(w, &cookie)
Then i'm trying to get it
func f2(w http.ResponseWriter, r *http.Request) {
...
cookie, err := r.Cookie("token")
fmt.Println(cookie.Value)
fmt.Println(cookie.Expires)
Output
valid_token_string
0001-01-01 00:00:00 +0000 UTC
Value is the same i set, but Expires is empty. Why?
