fragment caching -- expiring entire folders


I am using the file system store, and I need to expire entire folders on certain actions (i am trying to avoid the regexp key), but this is not supported. Below is my patch

Index: actionpack/lib/action_controller/caching.rb

Thanks for patch, but would you mind submitting it to the Rails Trac? It'd probably get better visibility there as a patch.

See for more info.
