title: Nodejs - how to make a quick get request without waiting for the answer
body: <p>I need to run a nodejs script that can send sequenced get http requests that may or may not be responded.</p>
  <p>This means that i can start by requesting , per example, 10.0.0.1  until 10.0.0.10 but it is possible that 10.0.0.4 and 10.0.0.5 does not exist at a given moment but i dont want that fact to slow down the requests to the other ip addresses and the reply of each ip address is not relevant. I don’t even read the reply. I just want to make the fastest and “blindest” request i can without nothing slowing down that process.</p>
  <p>How can i acheive that?</p>
  <p>Using xmlhttprequest as async. (I think. I’m not an experienced programmer or what-so-ever)
  But i could use some help on “how would you do it”.</p>
  <p>I’m using this to control some led lights that change color on the get request. I might not have them all connected to the router all the time and timing is very important, that’s why i dont need to check if the light has changed color or if it is active.</p>
  <p>Thank you for your help in advanced</p>
