mod_fastcgi versus mod_fcgid with apache2

Hello,

I am trying to better understand the differences between the two. (1) Once the modules installed, the apache.conf file must be adjusted with directives. Are the two modules similar in terms of options that can be set inside those directives?

(2) modfastcgi makes a difference between dynamic app (default with processes that may die) and static (the number of running app stays the same). Does modfcgid follow the same structure? Looking at mod_fcgid's docs, it is not obvious.

(3) which one is your favorite?

Thanks
