title: Throttling requests to a Ruby on Rails API
body: <p>Trying to Google around for an a Rails plugin that will allow for throttling the amount of requests a particular resource gets consumed. Django's <a href="http://bitbucket.org/jespern/django-piston/wiki/Home" rel="noreferrer">Piston</a> has some open source code for this. Is there something available out of the box for Rails or is it safe to assume that looking at how Piston does it and porting it as a Rails plugin is something that can be worked on?</p>
