Hi Manlio,

Thanks for reporting the bugs and sorry for the late reply.

I'm trying to compile the example WAI application, as defined in http://www.haskell.org/haskellwiki/WebApplicationInterface

However there are several bugs.

I haven't given the WAI specification much attention since I first wrote it.

I have noted that there is a WAI module in your Hyena web application server. http://github.com/tibbe/hyena I think that, instead, WAI should be defined in a separate package, that should contain: 1) WAI specification 2) WAI data types (hyena.Network.Wai.hs) 3) Some utility functions (see Python wsgiref module) 4) Standard implementation for CGI Since Haskell is not Python, it is necessary that both gateways and applpications use the same data types. Then, in separate packages, it is possible to implement support for SCGI, FastCGI and a simple HTTP 1.0 server (a full HTTP 1.1 server is not a priority, IMHO). IMHO, the WAI (or a separate) package should also contain support for parsing HTTP headers (to be used my both servers, gateways and applications). If there is a thing I hate, is when every project reinvent the wheel. One last note. I have some doubts about the name WAI. It means "Web application interface", but I think that the word "Gateway" should appear in it. Something like: HSGI ("Haskell Server Gataway Interface", that can also be read as "HTTP Server Gataway Interface"), or simply HGI ("Haskell Gateway Interface"). Manlio
