Regarding cookie

Question

I am setting a session cookie in one page using

setCookie("cookietime","1000");

And resetting it to "" on going back to previous page

setCookie("cookietime","");

When I go back I am showing an alert after seeting the cookie to "". it is showing "" in alert. But in the next page it still shows "1000". Is the cookie page specific

Answer 1

Cookies are stored client side and are computer+browser specific not page specific! I guess you are using document.cookie which should persist through the session - they persist even when the page is refreshed. Using window.name will only persist through the same browser window but will clear on page refresh. HTML5 localStorage may be a suitable alternative.
