设置为静态资源的HTTP标头的到期日或最长 [英] Set an expiry date or a maximum age in the HTTP headers for static resources

问题描述

我想提高一个ASP.NET MVC网站的性能。在这个过程中，我跑由谷歌PageSpeed​​ Insights工具。此工具提到，我应该通过设置HTTP头到期日或最高年龄的静态资源利用浏览器缓存。

一切我在网上找指出，在IIS的配置设置。我的挑战是，这个网站是微软Azure网站。出于这个原因，我没有访问IIS这个东西鼓捣。

有没有办法对我来说，这种应用程序的到期日期添加到HTTP标头为我的静态资源？如果是这样，怎么样？

感谢您！

解决方案

 保护覆盖无效初始化（System.Web.Routing.RequestContext的RequestContext）
    {
        requestContext.HttpContext.Response.Cache.SetCacheability（HttpCacheability.Public）;
        requestContext.HttpContext.Response.Cache.SetMaxAge（TimeSpan.FromSeconds（3600））;
        requestContext.HttpContext.Response.Cache.SetExpires（DateTime.UtcNow.AddSeconds（3600））;
        base.Initialize（RequestContext的）;
    }
 

I'm trying to improve the performance of an ASP.NET MVC website. In the process, I ran the PageSpeed Insights tool by Google. This tool mentioned that I should leverage browser caching by setting an expiry date or a maximum age in the HTTP headers for the static resources.

Everything I find online points out configuration settings in IIS. My challenge is, this site is a Microsoft Azure Website. For that reason, I do not have access to IIS to tinker with this stuff.

Is there a way for me to add expiry dates to the HTTP headers for my static resources in this kind of app? If so, how?

Thank you!

解决方案

        protected override void Initialize(System.Web.Routing.RequestContext requestContext)
    {
        requestContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.Public);
        requestContext.HttpContext.Response.Cache.SetMaxAge(TimeSpan.FromSeconds(3600));
        requestContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddSeconds(3600));
        base.Initialize(requestContext);
    }
