Right now I am using php on iis as isapi filter, but the problem is that whenever i request a missing .php file it gives me a blank page(when error_reporting is off) or include errors(if error_reporting is on) instead of giving me regular iis 404 html errors, i know this is most likely IIS problem, it probably is not checkign to see whether the php file even exists and trys to include it or run it and gets the errors or blank page, anyone know how to fix this?
