Cacheable

With RESTful web services, a client can cache any response coming from the server. The server can mention how, and for how long, it can cache the responses. With the caching option, a client can use the responses instead of contacting the server again. Also, caching will improve scalability and performance by avoiding client-server interactions all the time.

Since REST typically leverages HTTP, it inherits all the caching properties that HTTP offers.
