aspnetcore: HttpContext RequestAborted no longer works.

Describe the bug

Since .NET 6, the HttpContext.RequestAborted does not updates when the request is cancelled. This used to work with .NET 5. IsCancellationRequested stays in false even tho the request has been canceled and CanBeCancelled is set to true.

To Reproduce

I started a .NET 6 Angular project and created an HTTP GET request and subscribe to it, the Request is in an infinite loop intentionally so it can only be ended by the cancellation token. Also have a subject to cancel the request with an other button.

In .NET 5 this works flawlessly. In .NET 6 its unusable.

@singh733 you’re looking at the wrong method, that’s not how this works. I think you’re a bit in the weeds here. My guess is that the nodejs proxy (the client) isn’t disconnecting properly and that’s likely why the client isn’t seeing the disconnect.
