This plug allows for rate limiting HTTP calls to your application. It can be used in your controllers or the routing pipeline to e.g. rate limit per-IP traffic across your whole application and further restrict specific routes (e.g. login/password reset) further. A key to rate limit on can be chosen dynamically from the conn to allow for flexible limits.

plug ZerobsStack.RateLimitPlug, %ZerobsStack.RateLimitPlug{
  name: "PageController",
  identifier: [:private, :phoenix_format]
}

This sample show the usage in an exemplary PageController. The plug rate limits on 10 requests/60 seconds (default) and chooses the private/phoenix_format key from the conn. As with ZerobsStack.LoadShedPlug an error_controller key can be passed. This plug calls MyErrorController.call(conn, {:error, :rate_limit_reached}) so you can render a custom response.
