[Haskell-cafe] Lifetime control of webserver

My application is not a webserver but needs to run a webserver for part but
not all of its lifetime. Particularly, there's a part that does some
complex computation and I want a webserver to expose its internal
state/progress through HTTP.

It seems that the typical and expected way to use a webserver is to
designate the entire app itself as a webserver, so that functions like the
following are basically infinite loops that serve HTTP:



Can I run a webserver with explicit control of its lifetime? Particularly,
I want to be able to kill it without killing the app or explicitly serve
one request at a time. I'm not restricted to scotty or warp.
