This should do the trick:

    public static async Task CloneHttpRequestMessageAsync(HttpRequestMessage req)
    {
        HttpRequestMessage clone = new HttpRequestMessage(req.Method, req.RequestUri);

        // Copy the request's content (via a MemoryStream) into the cloned object
        var ms = new MemoryStream();
        if (req.Content != null)
        {
            await req.Content.CopyToAsync(ms).ConfigureAwait(false);
            ms.Position = 0;
            clone.Content = new StreamContent(ms);

            // Copy the content headers
            if (req.Content.Headers != null)
                foreach (var h in req.Content.Headers)
                    clone.Content.Headers.Add(h.Key, h.Value);
        }


        clone.Version = req.Version;

        foreach (KeyValuePair prop in req.Properties)
            clone.Properties.Add(prop);

        foreach (KeyValuePair> header in req.Headers)
            clone.Headers.TryAddWithoutValidation(header.Key, header.Value);

        return clone;
    }
