It is unsettling to see the "Content-Length" header printed in the diagnosis messages even though it is not actually present in the request and/or response headers.
Note that we can't just test whether the
ContentLength
property is null or not because the HttpContentHeaders.ContentLength implementation automatically computes a value even if the Content-Length is not present. This is why usingcontent.Headers.TryGetValues
is mandatory.
