Zend\Http\Client\Adapter\Curl does not send a proper DELETE request when request body is provided, hangs

[lucian303]

When providing a request body for a DELETE request, Zend\Http\Client will add the 'Content-Length' header but will not add and send the actual body resulting in a curl call that hangs for a very long period of time. The client should either send both a body and the header or neither. Since DELETE requests can have a body, I'd suggest sending both. From the IETF spec: "The presence of a message-body in a request is signaled by the inclusion of a Content-Length or Transfer-Encoding header field in the request's message-headers." -- http://tools.ietf.org/html/rfc2616

To fix, Zend\Http\Client\Adapter\Curl line 396 (ZF 2.2.7) should have an additional elseif to add the body to DELETE requests as well (or the 'Content-Length' header removed before sending the request), ideally the first option as below:

        } elseif ($method == 'DELETE') {
            curl_setopt($this->curl, CURLOPT_POSTFIELDS, $body);
        }
