Hi all,

I put a variable in my url ([www.domain.com/language/controller/](http://www.domain.com/language/controller/)  
action). The ‘language’ is always in the url and should be read out  
with every new call.

Do I need to read it out at the ApplicationController?

Regards,  
Stijn

No you don’t NEED to. However, the DRYist method for handleing this is  
probably to use it in an application wide filter
