BriskBard, CEF4Delphi, WebView4Delphi, WebUI4Delphi and WebUI4CSharp

I set GlobalCEFApp.DisablePDFExtension:=true;
I want to download pdf document but this showed in console:

jquery-1.9.1.js:14 Resource interpreted as Document but transferred with MIME type application/pdf:

if I canceled <GlobalCEFApp.DisablePDFExtension:=true;>
it will also show in console.

why this happened?
thank you!

That seems to be an error generated by a script in that web page and not in the web browser.

Use the TChromium.OnResourceResponse event and check the content-type header in the response parameter to download the PDF file with TChromium.StartDownload as you can see in this thread :
