The
mod rails people have riddle on there site and I think I have the answer now.
blue = Apache (prefork MPM) + Passenger
red = Apache (worker MPM) + Passenger
yellow = Nginx Mongel
green = Nginx Thin
gray = Litespeed
purple = Apache (worker MPM) + Ruby Enterprise Edition + Passenger
This could be incorrect but I am hoping I got it right. I am excited as a dream host user to try out mod_rails!!
