How could I use haxr (http://www.haskell.org/haskellwiki/HaXR) to build a stateful server?
It should listen on some port, and fork threads (inside Haskell land) to handle incoming calls. Any of the Haskell web frameworks can do this?
I guess this is the same question as: http://www.haskell.org/pipermail/haskell-cafe/2009-December/071185.html
Just an FYI for everyone. Johannes and I discussed this a bit off-list, and decided that the wai-frontend-monadcgi package would be a good fit for this use case. I deprecated this package because MonadCGI requires lazy I/O for the request body, and enumerator-based WAI 0.4 cannot provide a lazy request body[1]. However, WAI 1.0 will be based on conduits, which does allow lazy I/O. I've added the wai-frontend-monadcgi to the wai repository[2] and will release it when the rest of WAI 1.0 is released.
