# File 'lib/split.rb', line 71

def cache(namespace, key, &block)
  Split::Cache.fetch(namespace, key, &block)
end

#configure {|configuration| ... } ⇒ Object

Call this method to modify defaults in your initializers.

Examples:

Split.configure do |config|
  config.ignore_ip_addresses = '192.168.2.1'
end

Yields:

def configure
  self.configuration ||= Configuration.new
  yield(configuration)
end

#redis ⇒ Object

Returns the current Redis connection. If none has been created, will create a new one.

def redis
  return @redis if @redis
  self.redis = self.configuration.redis
  self.redis
end

#redis=(server) ⇒ Object

Accepts:

1. A redis URL (valid for `Redis.new(url: url)`)
2. an options hash compatible with `Redis.new`
3. or a valid Redis instance (one that responds to `#smembers`). Likely,
   this will be an instance of either `Redis`, `Redis::Client`,
   `Redis::DistRedis`, or `Redis::Namespace`.
