Hi,

I am trying to develop a native web view app and it is working good.

But every time I close and restart the app all login/cookie information is lost.

How can I store and restore cookies in a native web view?

What is very weird: The HTML5 Web Storage (local db) gets restored, but the cookies aren't available anymore!?

Do you have any information for me?

Here is the basic code that I am using (from a Samsung example):

#include "webviewexample.h"

// Header files needed for     EWK Webkit
#include <Ecore.h>
#include <Ecore_Evas.h>
#include <Ecore_Getopt.h>
#include <Eet.h>
#include <Eina.h>
#include <Elementary.h>
#include <Evas.h>
#include <EWebKit.h>
#include <app.h>
