title: HTTP requests without waiting for response
body: <p>Is it possible to send an HTTP request without waiting for a response?</p>
  
  <p>I'm working on an IoT project that requires logging of data from sensors. In every setup, there are many sensors, and one central coordinator (Will mostly be implemented with Raspberry Pi) which gathers data from the sensors and sends the data to the server via the internet.</p>
  
  <p>This logging happens every second. Therefore, the sending of data should happen quickly so that the queue does not become too large. If the request doesn't wait for a response (like UDP), it would be much faster.</p>
  
  <p>It is okay if few packets are dropped every now and then.</p>
  
  <p>Also, please do tell me the best way to implement this. Preferably in Java.</p>
  
  <p>The server side is implemented using PHP.</p>
  
  <p>Thanks in advance!</p>
  
  <p>EDIT:
  The sensors are wireless, but the tech they use has very little (or no) latency in sending to the coordinator. This coordinator has to send the data over the internet. But, just assume the internet connection is bad. As this is going to be implemented in a remote part of India.</p>
