What is REST API caching and how does it work?
REST API caching is a technique used to store responses from API calls to improve performance and reduce latency. It works by saving the response data for a specific request, so that subsequent requests for the same data can be served from the cache instead of querying the server again.
What are the benefits of using caching in REST APIs?
The benefits include reduced server load, faster response times, improved user experience, and lower bandwidth usage.
How can I implement caching in my REST API?
You can implement caching using HTTP headers like Cache-Control, ETag, and Last-Modified, or by using caching layers like Redis or Memcached.
Are there any downsides to caching?
Yes, potential downsides include stale data if the cache isn't updated properly, increased complexity in cache management, and potential cache misses.
