Description

I have switched from the Apache HttpAsyncClient 4 (4.1.4) library to the httpClient 5 (5.0.1)

I have found that when I make a POST call with body and get back a 307, the subsequent call does NOT include the data body any more, but it does still contain the Content-Type and Content-Length so the server then hangs waiting to receive the rest of the request which never comes.

 
I do not see anything like this while debugging in the HttpClient5 libs

FROM: org.apache.http.impl.client.DefaultRedirectStrategy

    public HttpUriRequest getRedirect(HttpRequest request, HttpResponse response, HttpContext context) throws ProtocolException {
        URI uri = this.getLocationURI(request, response, context);
        String method = request.getRequestLine().getMethod();
        if (method.equalsIgnoreCase("HEAD")) {
            return new HttpHead(uri);
        } else if (method.equalsIgnoreCase("GET")) {
            return new HttpGet(uri);
        } else {
            int status = response.getStatusLine().getStatusCode();
            return (HttpUriRequest)(status != 307 && status != 308 ? new HttpGet(uri) : RequestBuilder.copy(request).setUri(uri).build());
        }
    }

Here is an example from my logs
