Invalidating a cache

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.Fetching something over the network is both slow and expensive.Large responses require many roundtrips between the client and server, which delays when they are available and when the browser can process them, and also incurs data costs for the visitor.

This directive specifies the maximum time in seconds that the fetched response is allowed to be reused from the time of the request.All you need to do is ensure that each server response provides the correct HTTP header directives to instruct the browser on when and for how long the browser can cache the response.If you are using a Web View to fetch and display web content in your application, you might need to provide additional configuration flags to ensure that the HTTP cache is enabled, its size is set to a reasonable number to match your use case, and the cache is persisted.If the response is marked as "public", then it can be cached, even if it has HTTP authentication associated with it, and even when the response status code isn't normally cacheable.Most of the time, "public" isn't necessary, because explicit caching information (like "max-age") indicates that the response is cacheable anyway.
