Hi guys, I've noted that on some pages ResourceRequestHandler.OnResourceLoadComplete is never called for some requests. I tried this with the winforms example:

    public class MyRequestHandler : RequestHandler
    {
        private readonly MyResourceHandler reqHandler = new MyResourceHandler();

        protected override IResourceRequestHandler GetResourceRequestHandler(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IRequest request, bool isNavigation, bool isDownload, string requestInitiator, ref bool disableDefaultHandling)
        {
            return reqHandler;
        }
    }

    public class MyResourceHandler : ResourceRequestHandler
    {
        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);
        }
    }

Then set it like this on BrowserTabUserControl.cs:

browser.RequestHandler = new MyRequestHandler();

And then I loaded this page: https://www.ticketmaster.co.uk/

I get a call to OnBeforeResourceLoad with the URL https://www.ticketmaster.co.uk/api/cookies and identifier 902363, but never got a call to OnResourceLoadComplete with the same identifier (nor the same URL). I understand OnResourceLoadComplete should be called for all requests, so I wonder if this is a bug (probably unrelated to the one I mentioned before about browsers not being fully created sometimes).
