title: Sending an HTTP Post using Javascript triggered event
body: <p>I'm pretty new to javascript and am working on an embedded system which decodes video over IP.</p>
  
  <p>I have written a small app for setting up and changing channels using javascript and included a key handler for remote controls and an event handler so I can take some action or present a message if video stops or the network goes down, but now I also want to set up an automatic HTTP POST that gets sent when I change channel to include some data about the device and the url currently being played.</p>
  
  <p>This is a small embedded hardware device running busybox, so I can't use Ajax or add any other normal web technologies, I just need to use Javascript to send a HTTP POST triggered by events I am monitoring, so my first goal is to be able to press a button and send that POST message then work out when to trigger it later.</p>
  
  <p>Anyone familiar with doing such things that can give me a quick overview of how to send a post to a known listening device/location and include data in it?</p>
  
  <p>Many thanks</p>
