Topic: Dynamic CSS & Performance.
I have a need to one fairly large chunk of dynamic CSS. I'm aware there are various variations on the same separate controller/route system out there but from my understand of rails they're taking the fairly massive performance hit of an entire new rails process just to generate a CSS sheet.
I'm tempted to just dump it in the layout head but I'd like to keep it in a separate file if possible while being part of the same request so it's got access to instance variables etc. Isn't there some way with routes alone of getting Erb processed in a .css? The other option I guess is to move to edge rails where .xyz.erb is supported but I'd rather not for something that's going production in a few months.
