I wanted to setup really simple http server, found Network.CGI.Compat.pwrapper and decided it suits my needs. Code:
module Main where import Network.CGI import Text.XHtml import Network
doit vars = do return (body (toHtml (show vars)))
main = withSocketsDo (pwrapper (PortNumber 7777) doit)
Pointng any browser to http://127.0.0.1:7777 does not render the page. It seems the response headers are broken.
How do I report this bug (trac? something else?).
We might want to either fix it, or just get rid of it, as nobody seems to notice the problem :)

Hi Gracjan, pwrapper is not an HTTP server, though the Haddock comment can make you think so. pwrapper allows you to talk *CGI* over a TCP port, but I have no idea why anyone would like to do that. The functions in the Network.CGI.Compat module are deprecated, and shouldn't be used in new code. Even though I'm the maintainer of the cgi package, I don't really know what those functions could ever be useful for, and I've never seen any code which uses them. In fact, I've now removed the Network.CGI.Compat module and uploaded cgi-3001.0.0 to Hackage.
Another question is: how do I do equivalent functionality without pwrapper?
You can roll you own web server if you want something very simple. If you don't want to do that, there is a version of Simon Marlow's Haskell Web Server with CGI support [1]. You could also get the original HWS [2] and merge it with your program.
