How do I clear the cache of Cordova Web View on Windows Phone 8?

Question

I'm developing a Cordova 2.9.0 app for Windows Phone 8. The app in question utilises external content heavily, using the JS and HTML content that's being served from another source. It all works fine, but the browser component caches heavily.

The only way I have discovered to clear caches is to uninstall-install the app again to take effect. The downside to this is that my localStorage also clears, slowing down my cycles.

I presume the cache can be cleared by writing extra C# into the Cordova template they serve, which I use by the way.

So while it was not that critical, I did stumble to a working answer. The WebBrowser class does have a suitable method to call: ClearInternetCacheAsync.

Since CordovaBrowser inherits from WebBrowser, it's just a matter of adding one line to MainPage.xaml.cs where the C# init of the start page happens:

namespace FooBarApp
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
            this.CordovaView.Loaded += CordovaView_Loaded;
            // blammo!
            this.CordovaView.CordovaBrowser.ClearInternetCacheAsync();
        }
