          The following method will return if the value associated with a token/key is expired or not.



          def check_token_expiry(token)
          Rails.cache.read(token).nil?
          end


          Basically, try to read the value from cache. If it is expired, read method will return nil.

            When you specify the expires_in: 21.days while caching, you tell underlying cache store to store the data for given key(here token) for 21 days, after 21 days it gets expired means data is no longer available for the give key you use exist? method to check this.



            Rails.cache.exist?(token) # => true  (data is available and you read)
            Rails.cache.exist?(token) # => false (cache is expired, data is not available)
