Best Cache Practice

• Use Gulp, Webpack, or similar to add unique hash digits to css, js, and image files (like app-67ce7f3483.css);
• For js,css, and image files, set "Cache-Control: public, max-age=31536000", no Etag, no Last-Modified settings.
• For html files and API response, use "Cache-Control: no-cache" and Etag.
