Hi all,

I want to have a RESTful resource (because I need to use  
atom\_feed\_builder).

For the sake of the exemple, let say I need : map.resources :news

I want to be able to list all the news in index action, paginate it  
(using will\_paginate for example) and add cache to it each paginated  
page.

To add cache I need to have url like news/page/2, urls like  
news/?page=2 can’t be cached page by rails.

So any idea to solve this problem ?

## Thanks.

Nicolas C.

The answer was “use fragment caching”

# Controller

def index  
unless read\_fragment({:page =\> params[:page] || 1}) # Add the  
page param to the cache naming  
@news = News.paginate :all, :page =\> params[:page]  
end  
end

# View

## \<% cache ({:page =\> params[:page] || 1}) do %\> … All of the html to display the posts … \<% end %\>
