# File lib/roda/plugins/caching.rb, line 171 def cache_control(opts) values = [] opts.each do |k, v| next unless v k = k.to_s.tr('_', '-') values << (v == true ? k : "#{k}=#{v}") end @headers[RodaResponseHeaders::CACHE_CONTROL] = values.join(', ') unless values.empty? end
Specify response freshness policy for using the Cache-Control header. Options can can any non-value directives (:public, :private, :no_cache, :no_store, :must_revalidate, :proxy_revalidate), with true as the value. Options can also contain value directives (:max_age, :s_maxage).
response.cache_control public: true, max_age: 60 # => Cache-Control: public, max-age=60
See RFC 2616 / 14.9 for more on standard cache control directives: tools.ietf.org/html/rfc2616#section-14.9.1

Set Cache-Control header with the max_age given. max_age should be an integer number of seconds that the current request should be cached for. Also sets the Expires header, useful if you have HTTP 1.0 clients (Cache-Control is an HTTP 1.1 header).
