[plt-scheme] Controlling web-server

Is there a way to control the web server's execution?
I would like to stop or restart it (like with the Help Desk daemon). But
when I use it under Win98, it runs a 'invisible' tasks (only visible with
Ctrl+Alt+Suppr).
The only way I found to shut it down is to kill it using the Windows
"Program not responding" dialog box - even if the server actually works
well. A not very 'clean' way to do it.
I tried to use "web-server.exe -h", but I did not find anything on that.

Any clue?
