Server-side caching?involves storing frequently accessed data on the server. When a client requests data, the server first checks its cache. If the data is present (cache hit), it is served from the cache; otherwise, the server processes the request and may cache the result for future requests.
Usually it expires on it’s own after some time and gets refreshed. But otherwise you have to clear it manually. There a 100s of cache plugins and services that can run on the server so there’s no single way to clear each cache. Usually there’s a Clear/Purge cache button somewhere in WordPress Dashboard or your hosting panel account.
