Hi. This is probably "I must be blind department" I have a very basic strip down echo cgi that runs with apache2. When I try to modfi it to be a FastCGI instead and run it with spawn-fcgi with nginx It don't behave as expected. I suppose that the line that don't get any data is mn <- getInputFPS "file" when running under FastGCI. So is the code wrong? or have I missed something with the setup? I can run the example of fastcgi provided in http://mult.ifario.us/p/wiring-haskell-into-a-fastcgi-web-server with no problem.
