Day and Night playlist (.pls) change to stream url

[nscpro]

Hi.

If i use Liquidsoap example script which contains

day     = playlist("~/radio/day.pls")
night   = playlist("~/radio/night.pls")

How can i use day and night string which contain stream url. Example

day    = playlist("http://localhost:8000/day")
night  = playlist("http://localhost:8000/night") 

what should I change or what's right for the day and night stream to play instead of the playlist?

and i wish use Webcaster Client too..If i put Webmaster Client stream url to here

full =
  fallback(track_sensitive=false,
           [input.http("http://localhost:8000/live"),
            radio])

When Liquidsoap change playlist stream to live stream? if i click "start streaming" in webcaster client?
