Client is not reading complete response if neither Conten-Length nor Transfer-Encoding are set in header

I am trying to access a HTTP server which is responding with HTTP 1.1.

The client is not returning the full response from the server.

The options "Content-Lenght" and "Transfer-Encoding" are NOT present in the server's responses. But the option "Connection : close" is present. As I understand HTTP the option "Connection : close" should be enough to tell the client to read everything until the connection is closed by the server and treat all this data as part of the response.

If I insert the following code in std::shared_ptr<Response> request_read() everything works fine:

else if((header_it=response->header.find("Transfer-Encoding"))!=response->header.end() && header_it->second=="chunked") {
    request_read_chunked(response, chunked_streambuf);
} else if((header_it=response->header.find("Connection"))!=response->header.end() && header_it->second=="close") {
        auto timer=get_timeout_timer();
        boost::asio::async_read(*socket, response->content_buffer, boost::asio::transfer_at_least(1), [this, timer](const boost::system::error_code& ec, size_t /*bytes_transferred*/) {
        if(timer)
                timer->cancel();
        if(ec) {
            std::lock_guard<std::mutex> lock(socket_mutex);
            this->socket=nullptr;
            throw boost::system::system_error(ec);
        }
    });
 }
