Sources of the latest snapshot of Hugs serving
some simple example application via Fast-CGI framework
are available here:
http://www.numeric-quest.com/haskell/bridge/index.html
[I may consider giving access to my Hugs server
for testing to those from this list that I know
by their postings. But the installation is not
so complex - it just takes some time.]
Included are few HTML pages of documentation,
and auxiliary modules:
DateTime - this one really computes what it says
Md5Digest - The server uses it for authentication
but you can use it for other purposes too.
The main module Bridge.hs provides low level
interface to C, but its main strength is in presenting
the application programmers with really simple
model, which I shortly describe here:
--------------------------------------
type Environment = [(Name, Value)]
type Query = [(Name, Value)]
type Request = (Environment, Query)
serving_function :: Request -> IO ()
---------------------------------------
That's it! The request is just a glorified input,
and no one has to worry about where it has come from,
and in what form - POST, or GET, or whatever.
Writing fancy gadgets is a responsibility
of the application programmers, although I provide
some examples here too.
Aside from the basics, the Bridge.hs module
provides many examples and also a snapshot
of the simple application which is under
development and testing as I write this. The
application part requires some cleanup, but the
rest is quite decently designed and documented.
Enjoy,
Jan
