There are basically three ways you could interact with an Apache server from Haskell:
* CGI * FastCGI * Reverse HTTP proxy
Essentailly, in a reverse HTTP, you'll have a standalone server running on some port that never talks to the outside world, and Apache will proxy all HTTP connections for your application to that server. FastCGI is similar to CGI, except it allows for long-running processes, as opposed to spawning a new process for each request.
There are at this point three main web frameworks in Haskell (that I'm aware of, someone correct me if I'm wrong): Yesod[1], Happstack[2] and Snap[3].
Add MoHWS, a fork of Simon Marlow's HWS that I use for the online translation behind e.g. http://www.haskell.org.monadtransformer.parallelnetz.de/ . MoHWS has no support for building web formulars and processing and so on, but I found it very convenient to insert my online translation stuff into it.
