Subject Re: How do you use mod_perl for your web application?
Date Fri, 24 Jun 2011 04:45:29 GMT
One should really try mod_fcgid + perl application. that is lighter, faster,

mod_fcgid provides also authenticate/authorize/access controls, besides
dynamical content.
These are probably all you want to get from mod_perl.
