The getKeys method of the Cookie class returns an enumerator for a Cookie object, which you can use to access key values.
public wfc.util.IEnumerator getKeys();
The following Boolean function returns true if the cookie contains values, and false if it does not.
public Boolean checkgetkeys() { Request myRequest = AspContext.getRequest(); CookieDictionary myCookies = myRequest.getCookies(); Cookie myCookie = myCookies.getCookie("cookiedata"); Enumerator keylist = (myCookie.getKeys ()); if (keylist.hasMoreElements()) { //The cookie has key values return true } else { //it doesn't return false } }
