Does it mean one will be able to use it with webservers like Cherokee, nginx...?

Right now, the only WAI backends I'm aware of are the two I've written: SimpleServer and CGI. Assuming Cherokee and nginx support CGI, then yes, you could deploy there. That said, I intend to port hack-handler-fastcgi to WAI in the not-too-distant future. If anyone needs it sooner, just send me an e-mail, it will probably take very little time to port since it was simply a layer on top of hack-handler-cgi. Of course, there's a whole range of WAI backends that are possible. SimpleServer is not that great a production server, so I wouldn't mind getting Hyena or Happserver working with WAI. Then there are protocols like SCGI available as well. If we get really adventurous, we could aim for a mod_haskell. Michael

No, rush here, but the whole Yesod/WAI development looks quite encouraging that we can get solid platform for web development in Haskell pretty soon. :-)

What about Happs guys? Are they involved in WAI?

During the planning of WAI, they mentioned that Happstack uses the sendfile system call for optimizing sending of static files. WAI includes support for

If mod_haskell means Apache, we do not need it here preferring stuff like Cherokee/nginx/...

I also wouldn't have a use for mod_haskell, but it seems every "cool kid on

How do you like other players (Cherokee, nginx,...)?

Frankly, I haven't used either of those (though I came very close on Cherokee once). My most recent site[1] uses lighttpd and CGI, which I find to be a very nice setup. This way, I can avoid playing with virtual hosts at all in Haskell and still get a cookie-less domain ( http://static.search-once.com/).

Let me clarify my mod_haskell comment: I'm not saying I have no use for Apache, just that when I *do* use Apache, it's usually on a shared host where my only option is CGI. When I have full control over the deployment, Apache is usually too featureful for what I need. So unless mod_haskell got picked up by cheap shared web hosting (doubtful), I can't see a scenario where I'd end up using it. Michael [1] http://www.search-once.com/
