Find your favorite server in the list, look for the appropriate settings, and copy/confirm that your server is configured with the recommended settings.
From a performance optimization perspective, the best request is a request that doesn't need to communicate with the server: a local copy of the response allows you to eliminate all network latency and avoid data charges for the data transfer.
The server checks the token against the current resource.To achieve this, the HTTP specification allows the server to return Cache-Control directives that control how, and for how long, the browser and other intermediate caches can cache the individual response.The Cache-Control header was defined as part of the HTTP/1.1 specification and supersedes previous headers (for example, Expires) used to define response caching policies.If the token hasn't changed, the server returns a "304 Not Modified" response, which tells the browser that the response it has in cache hasn't changed and can be renewed for another 120 seconds.
Note that you don't have to download the response again, which saves time and bandwidth.
Check your server documentation for the necessary configuration flags.
