The web designer had web pages that he was trying to convert from Apache to nginx. Those pages were calling Perl programs from nginx using slowcgi.
I was the one that was configuring nginx. It would have made my life easier if a couple of points were added to the documentation. 1) that running "slowcgi -d" give extensive tracing information of all requests. (but remember to /etc/rc.d/slowcgi stop" first) 2) that all programs and their libraries have to be copied into /var/www 3) #! Lines are examined in text files and that information is used to find the programs, But no search rules are applied so you have to type #/usr/bin/perl Not #!perl
