Happstack.Server provides a self-contained HTTP server and a rich collection of types and functions for routing Requests, generating Responses, working with query parameters, form data, and cookies, serving files and more.

A very simple, \"Hello World!\" web app looks like:
> import Happstack.Server
> main = simpleHTTP nullConf $ ok "Hello World!"

By default the server will listen on port 8000. Run the app and point your browser at: <http://localhost:8000/>

At the core of the Happstack server we have the 'simpleHTTP' function which starts the HTTP server:

> simpleHTTP :: ToMessage a => Conf -> ServerPart a -> IO ()

and we have the user supplied 'ServerPart' (also known as,
'ServerPartT' 'IO'), which generates a 'Response' for each incoming

A trivial HTTP app server might just take a user supplied function like:

> myApp :: Request -> IO Response

For each incoming 'Request' the server would fork a new thread, run
@myApp@ to generate a 'Response', and then send the 'Response' back to
the client. But, that would be a pretty barren wasteland to work in.

The model for 'ServerPart' is essential the same, except we use the
much richer 'ServerPart' monad instead of the 'IO' monad. 

For in-depth documentation and runnable examples I highly recommend The Happstack Crash Course <http://happstack.com/docs/crashcourse/index.html>.
