module Rack; module Throttle
##
# 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.
#
# @example Allowing up to 86,400 requests per day
# use Rack::Throttle::Daily
#
# @example Allowing up to 1,000 requests per day
# use Rack::Throttle::Daily, :max => 1000
#
class Daily < TimeWindow

# @param [#call] app
# @param [Hash{Symbol => Object}] options
# @option options [Integer] :max (86400)
