Hi,
I have the following issue when starting my rails app. it does not seem like memcache is required but I still have the error.
I use the starter configuration from the doc (https://github.com/kickstarter/rack-attack/blob/master/docs/example_configuration.md)
I saw this issue that seem similar #163 but I didn't manage to pull a solution from it.
Is it my configuration that's bad or a problem with the gem ?
It works by installing the memcache gem in my gemfile, but if I want use redis, I should not need to add this dependency.

Hi @loicginoux,

Rails 3.2 compatibility is no longer "officially supported" since rack-attack 5.0+ (f6762df). That doesn't mean it won't work, but it means we don't test new changes against it, so we can't guarantee it will o will not work.

That said, from looking at the backtrace it seems that specific exception will probably go away if you use rack-attack 6.0+ instead of 5.4.2 because of #381. You may get other errors, as I said before.
