Add rate limit headers for Rack::Attack throttles.
Install the gem:
gem install 'rack-attack-rate-limit'
In your gemfile:
gem 'rack-attack-rate-limit', require: 'rack/attack/rate-limit'
And then execute:
bundle
Rack::Attack::RateLimit expects at least one Rack::Attack throttle to be defined:
Rack::Attack.throttle('my_throttle') do |req|
req.ip
end
To include rate limit headers for throttles, include the Rack::Attack::RateLimit middleware, and provide it with the names of the throttles you want to add rate limit headers for. A single throttle name can be provided as a string, while multiple throttle names must be provided as an array of strings.
For Rails 3+:
config.middleware.use Rack::Attack::RateLimit, throttle: ['my_throttle', 'my_other_throttle']
Rate limit headers are:
-
'X-RateLimit-Limit' - The total number of requests allowed.
-
'X-RateLimit-Remaining' - The number of remaining requests.
-
'X-RateLimit-Period' - The time period, in seconds, that the X-RateLimit-Limit applies to.
If a request triggers multiple throttles, the gem will add headers for the throttle with the lowest number of remaining requests.
