Rails - caching external HTTP calls

Question

My Rails application has to make a huge amount of external HTTP calls. Sometimes redundant HTTP calls process the request. So, I am looking for a way to cache external HTTP calls. The path should use memory to store cached data. Please, help.

It looks like you could just use Rails caching to accomplish this, although I haven't 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
