I’m trying to expire all pages under my view action. These could  
be /controller/view/1 or /controller/view/1/2

how can I expire all pages under /controller/view/? There must be a  
way, but I’m stumped. Here’s my broken attempt. Thanks in advance for  
any help,suggestions, or directions to a how to page.

expire\_action(:controller =\> ‘/pragmatic’,  
:action =\> ‘view’,  
:id =\> %r{\d\*},  
:page =\> %r{\d\*})

Still no luck here. I’ve also tried this but all it did was expire the  
view.html page  
expire\_action(:controller =\> ‘/pragmatic’,  
:action =\> ‘view’)

I’m interested in this as well… however for right now, I’ve taken this  
approach and modified it to suit my needs:

Thanks, it seems that is the route I’ll go untill I figure out how to  
just delete specific files under the public/controller/action directory.
