fragment_cache_key(value = nil, &key) Show source

Allows you to specify controller-wide key prefixes for cache fragments. Pass either a constant value, or a block which computes a value each time a cache key is generated.

For example, you may want to prefix all fragment cache keys with a global version identifier, so you can easily invalidate all caches.
