Class: Rack::Throttle::Daily

Inherits:
TimeWindow show all
Defined in:
lib/rack/throttle/limiters/daily.rb

Overview

This rate limiter strategy throttles the application by defining a maximum number of allowed HTTP requests per day (by default, 86,400 requests per 24 hours, which works out to an average of 1 request per second).

Note that this strategy doesn’t use a sliding time window, but rather tracks requests per calendar day. This means that the throttling counter is reset at midnight (according to the server’s local timezone) every night.

Examples:

Allowing up to 86,400 requests per day

use Rack::Throttle::Daily

Allowing up to 1,000 requests per day

use Rack::Throttle::Daily, :max => 1000
