Module: Dalli::Protocol::Meta::KeyRegularizer

Defined in:
lib/dalli/protocol/key_regularizer.rb

Overview

The meta protocol requires that keys be ASCII only, so Unicode keys are not supported. In addition, the use of whitespace in the key is not allowed. memcached supports the use of base64 hashes for keys containing whitespace or non-ASCII characters, provided the 'b' flag is included in the request.
