title: F# web server library
body: <p>Is there a web server library for F#, similar to SimpleHTTPServer in Python?</p>
  
  <p>Installing a full server like IIS is overkill for what I want, which is a simple application that can be queried using a web browser, effectively using HTTP as a monitoring method. Ideally, a request to the address <code>/engines/id/state</code> would map to a function <code>get_state(engine_id)</code> which I provide.</p>
