Hello,

I have a controller called user with an index action wich list all  
users.  
I can specify the order in the url like this /index/ordering/name/  
increasing.  
I have a lot of user so i use a params[:page] to list them like this /  
index/2.  
All work find.  
Next i want to cache my index action so in my user controller i put :

Code : - fold - unfold

1. caches\_action :index

Troubles arrive.  
When i go to /index a user.cache file is created.  
When i go to /index/2 a new cache file is created.  
But when i go to /index/ordering/name/increasing ,none file is  
created , the server give me the user.cache file created before , and  
my users are not ordered.

Thanks.
