Cancelling an HttpClient Request - Why is TaskCanceledException.CancellationToken.IsCancellationRequested false?

Question

Given the following code:

var cts = new CancellationTokenSource();

try 
{
    // get a \"hot\" task
    var task = new HttpClient().GetAsync(\"http://www.go         


        

Answer 1

I set the timeout to infinite to disable it, then I pass in my own cancellation token.

using(CancellationTokenSource cancelAfterDelay = new CancellationTokenSource(timespan/timeout))
...
catch(OperationCanceledException e)
{
if(!cancelAfterDelay.Token.IsCancellationRequested)
throw new TimeoutException($"An HTTP request to {request.Uri} timed out ({(int)requestTimeout.TotalSeconds} seconds)");
else
throw;
}
