Hi, I'm trying to implement a CGI, but I have encountered some problems with handling program errors properly. I think it boils down to this: The first program from the documentation at http://hackage.haskell.org/packages/archive/cgi/3001.1.5.2/doc/html/Network-... import Network.CGI cgiMain = output "Hello World!" main = runCGI (handleErrors cgiMain) works fine, and ouputs a page with the expected test. Replacing line 2 with: cgiMain = output $ error "Hello World!" returns a blank page, although according to the documentation, 'handleErrors' should produce an error page (500) instead. The error is recorded in the log, where one can read: [Thu May 22 14:35:27 2008] [error] [client 10.1.9.227] test.cgi: Hello World! I've toyed with various approaches, including using catchCGI and replacing 'error' with other run-time failures, but only getting the same result. Any hints? (ghc 6.8.1, cgi-3001.1.5.1, apache 2.0, linux.) -k -- If I haven't seen further, it is by standing in the footprints of giants
