 NSMutableArray *cookieArray = [[NSMutableArray alloc] init];
    for (NSHTTPCookie *cookie in [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]) {
        [cookieArray addObject:cookie.name];
        NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
        [cookieProperties setObject:cookie.name forKey:NSHTTPCookieName];
        [cookieProperties setObject:cookie.value forKey:NSHTTPCookieValue];
        [cookieProperties setObject:cookie.domain forKey:NSHTTPCookieDomain];
        [cookieProperties setObject:cookie.path forKey:NSHTTPCookiePath];
        [cookieProperties setObject:[NSNumber numberWithInt:cookie.version] forKey:NSHTTPCookieVersion];

        [cookieProperties setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

        [[NSUserDefaults standardUserDefaults] setValue:cookieProperties forKey:cookie.name];
        [[NSUserDefaults standardUserDefaults] synchronize];

{

    NSMutableArray* cookieDictionary = [[NSUserDefaults standardUserDefaults] valueForKey:@"cookieArray"];
     NSLog(@"cookie dictionary found is %@",cookieDictionary);

    for (int i=0; i < cookieDictionary.count; i++)
{

        NSLog(@"cookie found is %@",[cookieDictionary objectAtIndex:i]);
        NSMutableDictionary* cookieDictionary1 = [[NSUserDefaults standardUserDefaults] valueForKey:[cookieDictionary objectAtIndex:i]];
        NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieDictionary1];
        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
