// callback:
// Callback interface used for asynchronous continuation of url requests.

// Returns:
// To cancel loading of the resource return CefSharp.CefReturnValue.Cancel or
// CefSharp.CefReturnValue.Continue to allow the resource to load normally.
// For async return CefSharp.CefReturnValue.ContinueAsync
