Compare with:

fragment_cache_key(key)

Given a key (as described in expire_fragment), returns a key suitable for use in reading, writing, or expiring a cached fragment. If the key is a hash, the generated key is the return value of url_for on that hash (without the protocol). All keys are prefixed with “views/” and uses ActiveSupport::Cache.expand_cache_key for the expansion.

Parameters

key req
