Overview

Cache utilizing a DRb server.

You will need to run a corresponding DRb server to use this cache. The example below is using a normal Hash, but it is recommended to use a thread-safe alternative like SyncHash.

Example for DRb server:

require 'drb'

URI = "druby://127.0.0.1:9069"
CACHE = {}

$SAFE = 1 # disable eval and friends

DRb.start_service(URI, CACHE)
DRb.thread.join

Usage for all caches:

Innate.options.cache.default = Innate::Cache::DRb

Usage for sessions only:

Innate.options.cache.session = Innate::Cache::DRb
