I am using Perl code from an old book that refers to mod_fastcgi but I have
mod_fcgid installed. I had to comment out some code ( before exit) and change
Accept() to eliminate some errors in conf/error_log. However, I still get a 500
instead of what is desired and a message saying: AuthUserFile not specified in
the configuration. As I understand it, the script should take its place.
Thanks again.
