[Haskell] Trying On Learn Haskell Web Server

Hi all, I am former imperative programmer (Java/C/Python) I have recently discovered Haskell and read through "Yet Another Haskell Tutorial" (the best I have found) and "Tackling The Awkward Squad". This paper mentions a Haskell Web Server (HWS) but I am not able to find the source. Where can I find the source? Has this code been updated since the paper was written? Can it be compiled and run on a recent version of GHC?Hugs? I would like to use it as an example program to teach myself Haskell. Thanks... Deech
