Rails - Caching external HTTP calls

Question

My Rails app has to make a massive amount of external http calls. Sometimes, redundant http calls to handle a request. So, I'm looking for a way to cache external http calls. The way should use memory to keep cached data. Please help.

It seems like you could just use Rails caching to accomplish this, though I haven't actually tested it.

results = Rails.cache.fetch(cache_key) do  # You could use a unique URL as part of the cache key
  # HTTP request
  # Return results from processing the response
end
