Usage
Use as a home page cache, expired within 120 second.
# The first step is need specify a namespace, one string which should unique each other
# for different purpose, in this current case (one Rails controller action), `request.url'
# is a perfect candidate.
cacher = SimpleCacher.new(namespace: request.url)
if cacher.fresh?(key: 'items')
@items_hash = cacher.import(key: 'items')
else
# do something get correct data and assign to a variable items_hash
@items_hash = cacher.export(key: 'items', data: items_hash, expire: 120)
endUse as a counter, limit IP access during a time span.
counter = SimpleCacher.new(namespace: 'my_api:sms_log:user_ip')
# Sum IP 123.123.123.123 access count in one day,
if counter.reach_limit?(key: '123.123.123.123', limit: 5, expire: 86400)
