Which HTTP method can be cached?

The HTTP methods GET and HEAD are cacheable by default. This means that responses to requests with these methods can be stored in the browser or proxy cache for reuse, which improves performance and reduces server load.

Other methods, such as POST, PUT, DELETE, are usually not cached because they modify the server state. However, in some cases, caching can be configured for them if it is justified and safe.

Example: when making a GET request to the resource /api/products, the browser may save the response and use the cache for subsequent requests if the server does not specify other caching headers.
