Configure Nginx web page caching time

When Nginx returns the web page data to the client, the caching time can be set to facilitate the direct return of requests for the same content in the future, avoiding repeated requests and speeding up the access speed. Generally, it is set for static web pages, but not for dynamic web pages. You can use fiddler in the Windows client to view the page cache time.

Setting method

You can modify the configuration file to add expired parameters for specific content in the http section, or the server section, or the location section
