Hi.
I'm very new to Haskell.


 From the SoC2008 page I see that there is a project for working on a 
mod_haskell for Apache.

Now, I'm the author of the WSGI (Python Web Server gateway Interface) 
module for Nginx:

http://hg.mperillo.ath.cx/nginx/mod_wsgi/


I'm thinking about writing an Haskell module for Nginx, for learning 
purpose.

I'm not a student, so this is not a SoC2008 proposal, but I'm very 
interested in related works.


As an example, how should be a CGI like interface for Haskell?


Since Nginx is asynchronous, how can be solved the producer-consumer 
problem (that is, the Haskell program produces more data that Nginx can 
send to the client without blocking)?

I have easily solved this in Python, since the WSGI application returns 
a generator and I can simply suspend the iteration.


Is it possible to support asynchronous Haskell applications (as an 
example an application that needs to do a HTTP request to a server 
without blocking the worker process)?

Here, again, I have solved the problem for Python by making use of 
generators:
http://hg.mperillo.ath.cx/nginx/mod_wsgi/file/tip/examples/nginx-postgres-async.py

(but this is very experimental)




Thanks and sorry for having used this thread for an unrelated topic
(I have removed the Cc to haskell-soc-2008)
