I dont have the exact source code, but this is one possible solution.

Make sure the page has a unique title. Launch the URL.
FindWindow by Title and get the handle.

Send WM_CLOSE to the window using the handle.

psuedocode

LaunchURL "myURL"
HANDLE myHandle = FindowWindowByTitle("TITLE OF MY URL")
SendMessage myHandle,WM_CLOSE,0,0

Hope this helps.
