[Haskell] Haskell based web server?

[Gregory Woodhouse]

I've been reading the article "Tackling the Awkward Squad" by Simon  
Peyton Jones (and find it very readable and useful, BTW). I wonder if  
the HTTP/1.1 server referred to in this article is available on the  
web. If not, where else can I look for examples of TCP/IP based  
server applications written in Haskell? I ask because I'm very much a  
Haskell newbie, but have spent several years developing interfaces  
for medical information systems based on HL7, and am interested  
(among other things) in the possibilities of using Haskell to develop  
safety critical systems.
