Hi guys,

I am having this issue on my app.

Maybe I manage to make it work on the simulator after find this post

http://stackoverflow.com/questions/25853470/shared-nsurlcache-and-uiwebview-on-ios-8
http://inessential.com/2007/02/28/figured_it_the_heck_out

I am using cordova 6.3.0 and cordova ios 4.2.0

Ive tested in ios sim with Ios 8.4 and 9.3 images and its working but tested in Iphone 4 Ios 7 Device and didnt worked.
My iphone 5s battery broke so i can test on real iphone 5 that was ios 8.4

I have changed the file: [project_name]/app/platforms/ios/[project_name]/Classes/AppDelegate.m

This

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    self.viewController = [[MainViewController alloc] init];
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

To This

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    NSURLCache *URLCache = [[NSURLCache alloc] initWithMemoryCapacity:4 * 1024 * 1024 diskCapacity:20 * 1024 * 1024 diskPath:nil];
    [NSURLCache setSharedURLCache:URLCache];
    self.viewController = [[MainViewController alloc] init];
    return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

But that was just a shot in the Dark, i dont really know what i did so maybe you can do better.

Also i made a test with wkwebview-engine (the one that comes with a plugin to make local webserver) and there this was working without i change the app delegate file

Thank you!

>    Affects Versions: 2.5.0
>            Reporter: Shazron Abdullah

> I have this report from a developer:
> We've recently upgraded from 2.2 to 2.5 on IOS.
> In 2.2, our application leveraged cached assets after a complete restart of the application.  In 2.5 the same scenario always requests new assets from the web server.  The web server has not changed, and it returns caching instructions with the content.  Once the application is running, the cached assets are utilized as we expect.
> Is this by design?
