Answer 1

Make your application when it is finished write to file /somedir/yoursecretfile

If using linux, make a cron job which check periodically if file /somedir/yoursecretfile exist and if the file exists, stops a web server (maybe with ps | grep | xargs or something like that).

If using other OS, use replacement for cron for that OS and script which stops a webserver.
