This sample project demonstrate how the Timeout when using HttpClientTimeoutHandler does not include reading the response unlike the default HttpClient behavior. It's similar to using HttpCompletionOption.ResponseHeadersRead.

HttpClientTimeoutHandler is from https://www.thomaslevesque.com/2018/02/25/better-timeout-handling-with-httpclient/. Also, the code directly in the post does not use .ConfigureAwait(false) and it should.
