问题描述
有关如何在asp.net应用程序中做浏览器缓存的任何建议。我发现了一些不同的方法在网上，但不知道什么是最好的。具体来说，我想我的缓存CSS和JS文件。它们做改变，但是，它通常是每月一次至多。
Any suggestions on how to do browser caching within a asp.net application. I've found some different methods online but wasn't sure what would be the best. Specifically, I would like to cache my CSS and JS files. They do change, however, it is usually once a month at the most.
推荐答案
另一种方法是你存储静态图像，CSS和JS另一台服务器上（如的），其中有Expires头设置正确。这样做的好处是双重的：
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:
- Expires头将鼓励浏览器和代理缓存这些静态文件
- 的CDN将您的服务器提供静态文件卸载。
- 将使用其他域名的静态内容，浏览器会下载速度更快。这是因为从四五个不同的主机名服务资源
- 如果CDN的配置正确，并使用<一个href=\"http://$c$c.google.com/speed/page-speed/docs/request.html#ServeFromCookielessDomain\">cookieless域那么你没有不必要的饼干来回。
- The expires header will encourage browsers and proxies to cache these static files
- The CDN will offload from your server serving up static files.
- 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.
- If the CDN is configured properly and uses cookieless domain then you don't have unnecessary cookies going back and forth.
