Another technique is to stores you static images, css and js on another server (such as a CDN) which has the Expires header set properly. The advantage of this is two-fold:

1. expires标头将鼓励浏览器和代理缓存这些静态文件


2. CDN将从提供静态文件的服务器卸载。


3. 通过为静态内容使用其他域名，浏览器将下载速度更快。这是因为从四个或五个不同的主机名提供资源会增加下载的并行性。


4. 如果CDN配置正确，并使用 cookieless domain ，则您没有不必要的Cookie来回。

1. The expires header will encourage browsers and proxies to cache these static files
2. The CDN will offload from your server serving up static files.
3. By using another domain name for your static content, browsers will download faster. This is because serving resources from four or five different hostnames increases parallelization of downloads.
4. If the CDN is configured properly and uses cookieless domain then you don't have unnecessary cookies going back and forth.
