Help with restful like interface

Thanks, I had looked at the examples and have used it previously, clearly I needed to sleep on it but I think I get it now.

I could type:

192.168.0.13/set?23

function onPageRequest(req, res) {
  var a = url.parse(req.url, true);
  if (a.pathname=="/set") {
targetRoomTemp= a.query
}

to change the varible 'targetRoomTemp' to 23?

Or with 192.168.0.13/set/23

function onPageRequest(req, res) {
  var a = url.parse(req.url, true);
  'a.pathname'.split('/')==[1,2,3];

  if (a.pathname(2)=="/set") {
targetRoomTemp= a.pathname(3);
}
