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. You might also be interested In HAppS [3].
Haskell Web Server seems to be the closest match. I don't want fully functional web server. I need more low level thing, as I need to set this up as a testing environment for some other (browser like) application. So I need a way to trigger (atrificial) errors, like protocol errors, garbage and broken connections. Thanks for the response. Is there a description what is a *CGI* protocol? -- Gracjan
