OnBeforeResourceLoad

[derbuchmann]

Hi,
i am using cefsharp 86.0.0 and it is really great. Thank You so much.
But I have a question?
I want to add a request header ( a identifier). I do it on the ResourceRequestHandler.OnBeforeResourceLoad an it works!
But not with YouTube!!!
When I add a header, no video plays anymore!
I also put the headername to the "Access-Control-Request-Headers", but nothing helps.

Can someone maybe help?
Thank you

The short version is only add headers to sites that are within your control or that you've tested and have confirmed support handling pre flight requests.

See #3277 for further details. I'd also suggest reading https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#simple_requests
