This module provides for execution of CGI scripts. ... Module Identifier: cgi_module Any file that has the mime type application/x-httpd-cgi or handler cgi-script (Apache 1.1 or later) will be treated as a CGI script, and run by the server, with its output being returned to the client. ... Debugging CGI scripts has traditionally been difficult, mainly because it has not been possible to study the output (standard output and error) for scripts which are failing to run properly. ...
