Hi Everybody, I'm having some strange issues with Network.CGI's pathInfo action, or else some other strangeness with pattern matching. My "mainCGI" CGI action is: mainCGI :: CGI CGIResult mainCGI = pathInfo >>= outputSlotTHtml . packagesPage outputSlotTHtml is irrelevant to my problem. packagesPage generates a SlotT IO Html -- Slot semantics are essentially irrelevant to my problem. But packagesPage calls a function called pathCrossRef which is having some problems: packagesPage :: WebPath -> SlotT IO Html packagesPage wp = do infos <- getPackageInfos . pathCrossRef $ wp ... pathCrossRef :: String -> String pathCrossRef "/working/" = "/development/code/haskell/working/" pathCrossRef _ = "/development/code/haskell/packages/" The intention is that when the cgi program is called with "/working/" as an argument, the pathCrossRef should point at "/development/.../working/", and when called with "/packages/" (or anything else) as an argument, pathCrossRef should point to "/development/.../packages/". But it is not working! When I visit http://localhost/working/, I end up using the "packages" cross ref. I have even printed the cgi argument to the Apache log, and the argument is "/working/". If I get rid of the wildcard pattern, I get a "missing pattern" error when I visit http://localhost/working/. Can anybody help? Thanks, Alex
