Cefsharp clearing cache,cookies and browser data in wpf

I found the answer! It was because of disabling cache setting. By doing so, it actually caches the data but it won't be accessible. For example, you can't remove cookies without shutting down CEF. So, if you enable cache setting (leave it as the default), you can remove them with Cef.GetGlobalCookieManager().DeleteCookies("", "").
