WifiNina: Keep open connection after read something.

Hi,

I would like to make a get on an url and read the returned json.
I send info to my server, and he answers me. Unfortunately the connection is shutdown once in two.

Any Idea ? Is there a way to keep the connection open, because the conect() take 1-2 seconds

Thanks.

     int success = 1;
    // If we're not connected, open the connection.
    if(!clientPosition.connected())
    {
        Serial.println("connection restablished");
        success = clientPosition.connect(server,80);
    }
    else
      Serial.println("Connected");

      clientPosition.println(watchMoving);
      clientPosition.print("Host: ");
      clientPosition.print(server);
      clientPosition.println(":80");
      clientPosition.println("Connection: keep-alive");
      clientPosition.println();
      clientPosition.flush();

      while (clientPosition.available()) {
        char c = clientPosition.read();
        Serial.write(c);
      }

just an update of my request.
The purpose is just to realize a http get, so i don't really understand why to make a http connect
