I’m running latest version of RoR under Apache 2 (using a virtual  
host), if I change the environment config within the virtual host  
(SetEnv RAILS\_ENV development) then it changes environment as  
expected.

However when I’m working with views and not the model I would like  
have RoR cache the model files, I have tried changing the value of  
config.cache\_classes to true in the config/environment/development.rb  
file but that doesn’t seem to make any difference.

I’ve not tried WEBrick or anything else, I just jumped straight into  
Apache 2 as that is how it will be deployed on the live servers.

Any ideas why this isn’t working?
