Hi, I am doing some tests with Haskell to produce CGI programmes. I am running Microsoft IIS 5.0 as the weberver executing haskell compile executables that are cgi. If I set the header with a content type, Firefox always reports the content-type as application/octet-stream, and tries to initiate a download. IExplorer 6.0 does not report the type at all. It seems like the setHeader function does not result in sending headers. Has anyone seen this problem. Code snippet here ==== main :: IO() main = runCGI $ handleErrors cgiMain cgiMain :: CGI CGIResult cgiMain = do x <- getVars y <- getInputs prog <- progURI query <- queryURI request <- requestURI path <- pathInfo inputs <- getInputs setHeader("Content-type" "text/plain") setCookie (Cookie "bbb" "hello" Nothing Nothing Nothing False ) liftIO (putStr "asdfasdf") output $ (uris "prog" prog) ++ (uris "query" query) ++ (uris "request" request) ++ "\npath: " ++ path ++ "\n" ++ (varsToString inputs) ++(varsToString x) ++ "\n\nVars\n"++ (varsToString y)
