How to use Rack::Attack with a cache prefix?

Question

We're running several apps against the same Memcached, so I'd like to configure different prefixes for all apps using Rack::Attack. By default, several apps would overwrite each others' cache.

I've seen the prefix accessor in Rack::Attack::Cache and there's even a low-level spec for it but there are no examples on how to use it.

According to the README and the introductory blogpost, I never have to deal with Rack::Attack::Cache but always with the higher-level Rack::Attack.

So, how can two or more apps use the same memcached for Rack::Attack without overwriting each others' cache keys?

Answer 1

Rack::Attack.cache.prefix = "custom-prefix"

Rack::Attack.cache is an instance of the Rack::Attack::Cache class.
