When an HTTP cache header is set, the document can be cached to these network resources, so that you do not have to return the original server to respond to client requests.However, using the page output cache does not make your application more efficient, but it can potential

This not only greatly reduces the response time, but also makes it easy to implement distributed static content due to the presence of CDN.CDN is a collection of geographically distributed Web servers for more efficient content publishing. Generally, the web server is selected for a specific user based on the network distance.Some large websites own their own CDN, but use
