My website is mainly a single controller/action and the menu/page is  
chosen by passing the parameters  
params[‘menu’]  
params[‘submenu’]

after rerouting, the urls look like this:

[www.mywebsite.com/:menu/:submenu](http://www.mywebsite.com/:menu/:submenu)

I’d like to cache every url, since caching the whole action doesn’t  
seem to do anything at all…

How can I approach this problem?  
bye

Sounds like you’re looking for page caching.

The API docs on page caching can be found at:

[http://api.rubyonrails.com/classes/ActionController/Caching/Pages.html](http://api.rubyonrails.com/classes/ActionController/Caching/Pages.html)

thanks, I did it but I still have some problem. I decided that I’ll  
leave this when my app goes on the server now I don’t to get an  
headache for nothing…

thanks  
bye

In what environment are you testing your caching? IIRC caching only  
works in the “production” environment and not in “development”.
