Here is my post on how to make a https call. http://srikanthjeeva.blogspot.in/2010/06/making-httphttps-post-request.html Spent a long time in figuring out how to send a https request under a proxy Here is how it is, require 'net/http' require 'net/https' require 'uri' uri  = URI('https://IP/api/V1/USERS') proxy_class = Net::HTTP::Proxy(PROXY_ADDRESS, PROXY_PORT, USERNAME, PASSWORD) proxy_class.start(uri.host, uri.port, :use_ssl => uri.scheme == 'https', :verify_mode => OpenSSL::SSL::VERIFY_NONE) { |http|   request = Net::HTTP::Get.new uri.request_uri   response = http.request request   puts response.body } Hope this helps. Thanks!

Rails has wonderful inbuilt caching methods. This is how i implemented caching for a particular action.   Requirement : Cache a page for 12 hours. After 12 hrs Caching must expire.   before_filter :clear_cache   caches_action :index, :layout => false def index       #code     # Write expiry time to cache (12 hours)     Rails.cache.write('expiry_time', Time.now + 12.hours) end def clear_cache     #Fetch time from cache and check with current time     t = Rails.cache.fetch('expiry_time') || Time.now     t = Time.parse(t) if t.is_a?(String)     # Expire action if current time > Cached time     expire_action :action => :index if Time.now > t  end Thanks!
