cefsharp/CefSharp

@larouchefrancois I tried what you suggested:

    public class MyRequestHandler : RequestHandler
    {
        protected override IResourceRequestHandler GetResourceRequestHandler(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IRequest request, bool isNavigation, bool isDownload, string requestInitiator, ref bool disableDefaultHandling)
        {
            return new MyResourceHandler();
        }
    }

    public class MyResourceHandler : ResourceRequestHandler
    {
        protected override bool OnResourceResponse(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IRequest request, IResponse response)
        {
            System.Diagnostics.Debug.WriteLine($"OnResourceResponse [{request.Identifier}]: {request.Url}");
            return base.OnResourceResponse(chromiumWebBrowser, browser, frame, request, response);
        }

        protected override CefReturnValue OnBeforeResourceLoad(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IRequest request, IRequestCallback callback)
        {
            System.Diagnostics.Debug.WriteLine($"OnBeforeResourceLoad [{request.Identifier}]: {request.Url}");
            return base.OnBeforeResourceLoad(chromiumWebBrowser, browser, frame, request, callback);
        }

        protected override void OnResourceLoadComplete(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IRequest request, IResponse response, UrlRequestStatus status, long receivedContentLength)
        {
            System.Diagnostics.Debug.WriteLine($"OnResourceLoadComplete [{request.Identifier}]: {request.Url}");
            base.OnResourceLoadComplete(chromiumWebBrowser, browser, frame, request, response, status, receivedContentLength);
        }
    }

But only got these two:

OnBeforeResourceLoad [863083]: https://www.ticketmaster.co.uk/api/cookies
OnResourceResponse [863083]: https://www.ticketmaster.co.uk/api/cookies

No call to OnResourceLoadComplete except after I navigated away again, I guess because CEF disposed the request:

OnResourceLoadComplete [863083]: https://www.ticketmaster.co.uk/api/cookies

So I wonder if you're doing something else that I'm not. I literally just downloaded the latest version of CefSharp and added the code. I originally thought it worked but it was because I added some code to ignore this specific request which then forgot to remove.
