Which is the best way to cache a rest request?
Since REST is an HTTP thing, it could be that the best way of caching requests is to use HTTP caching. Look into using ETags on your responses, checking the ETag in requests to reply with ‘304 Not Modified’ and having Rack::Cache to serve cached data if the ETags are the same.
Do you need to explicitly disable caching for REST services?
Short: yes, caches may cache the response even if no explicit controls are present, you need to explicitly disallow it. The HTTP caching specification Section 3 lists when the response is forbidden to be cached. It suggests that the response may be cached as long as the response code is cacheable.
What happens if there is no cache in the request?
If none of the caches can satisfy the request, the request travels to the service (or origin server as it is formally known). By using HTTP headers, an origin server indicates whether a response can be cached and, if so, by whom, and for how long.
How does caching work in a web service?
Caching is the ability to store copies of frequently accessed data in several places along the request-response path. When a consumer requests a resource representation, the request goes through a cache or a series of caches (local cache, proxy cache, or reverse proxy) toward the service hosting the resource.
What is the default value for the requestcache?
A RequestCache value. The available values are: default — The browser looks for a matching request in its HTTP cache. If there is a match and it is fresh, it will be returned from the cache. If there is a match but it is stale, the browser will make a conditional request to the remote server.
How to implement caching mechanism for REST APIs?
You need to implement it. That means: on the server side you need to add caching directives and entity tags, and implement this mechanism together with an actual cache that sits in front of your DB (frameworks usually have support for things like this up to some point – so they might get you part of the road there). clients need to play nice.
What kind of cache does the API platform use?
API Platform internally uses a PSR-6 cache. If the Symfony Cache component is available (the default in the API Platform distribution), it automatically enables support for the best cache adapter available. Best performance is achieved using APCu. Be sure to have the APCu extension installed on your production server.
