Multiple files on CDN vs. one file locally

由 雨燕双飞 提交于 2019-12-17 21:26:44
问题 My website uses about 10 third party javascript libraries like jQuery, jQuery UI, prefixfree, a few jQuery plugins and also my own javascript code. Currently I pull the external libraries from CDNs like Google CDN and cloudflare. I was wondering what is a better approach: Pulling the external libraries from CDNs (like I do today). Combining all the files to a single js and a single css file and storing them locally. Any opinions are welcome as long as they are explained. Thanks :) 回答1: The

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . So, I have a dedicated server. I host about dozen or so small sites. Is there a real benefit in using S3(or Mosso) for my image and static file hosting? My server has more than enough disk space, or am I completely missing the point of S3? I keep reading about how wonderful and cheap it is, and I ask myself

How to upload bundled and minified files to Windows Azure CDN

由 我的梦境 提交于 2019-12-17 17:33:32
问题 I'm using the ASP.NET MVC 4 bundling and minifying features in the Microsoft.AspNet.Web.Optimization namespace (e.g. @Styles.Render("~/content/static/css") ). I'd like to use it in combination with a Windows Azure CDN. I looked into writing a custom BundleTransform but the content is not optimized there yet. I also looked into parsing and uploading the optimized stream on runtime but that feels like a hack to me and I don't really like it: @StylesCdn.Render(Url.AbsoluteContent( Styles.Url("~

How to link files directly from Github (raw.github.com)

问题 Are we allowed to link files directly from Github ? <link rel="stylesheet" href="https://raw.github.com/username/project/master/style.css"/> <script src="https://raw.github.com/username/project/master/script.js"></script> I know this is allowed on Google Code. This way I don't have to worry about updating a local file. 回答1: Yes. It's even update safe unless someone changes history in git and forces a push. In other words the content is versioned. 回答2: The great service RawGit was already

Why use protocol-relative URLs at all?

由 自闭症网瘾萝莉.ら 提交于 2019-12-17 05:01:49
问题 It's been an oft-discussed question on StackOverflow what this means: <script src="//cdn.example.com/somewhere/something.js"></script> This gives the advantage that if you're accessing it over HTTPS, you get HTTPS automatically, instead of that scary "Insecure elements on this page" warning. But why use protocol-relative URLs at all? Why not simply use HTTPS always in CDN URLs? After all, an HTTP page has no reason to complain if you decide to load some parts of it over HTTPS. (This is more

Closed 5 months ago . We're currently pulling jQuery and jQueryUI (and jQueryUI CSS) libraries from the google CDN. I like this because I can call google.load("jquery", "1"); and the latest jQuery 1.x.x will be used. Now I am to pull the libraries locally because of security. I'm happy to pull them

CDN 全称:Content Delivery Network或Content Distribute Network，即内容分发网络 是将源站内容分发至最接近用户的节点，使用户可就近取得所需内容，提高用户访问的响应速度和成功率。解决因分布、带宽、服务器性能带来的访问延迟问题，适用于站点加速、点播、直播等场景。 基本思路 尽可能避开互联网上有可能影响数据传输速度和稳定性的瓶颈和环节，使内容传输的更快、更稳定。通过在网络各处放置节点服务器所构成的在现有的互联网基础之上的一层智能虚拟网络，CDN系统能够实时地根据网络流量和各节点的连接、负载状况以及到用户的距离和响应时间等综合信息将用户的请求重新导向离用户最近的服务节点上。 目的 解决因分布、带宽、服务器性能带来的访问延迟问题，适用于站点加速、点播、直播等场景。使用户可就近取得所需内容，解决 Internet网络拥挤的状况，提高用户访问网站的响应速度和成功率。 控制时延无疑是现代信息科技的重要指标，CDN的意图就是尽可能的减少资源在转发、传输、链路抖动等情况下顺利保障信息的连贯性。 CDN就是扮演者护航者和加速者的角色，更快准狠的触发信息和触达每一个用户，带来更为极致的使用体验。 基本原理 cdn最简单的CDN网络由一个DNS服务器和几台缓存服务器组成： 打打 1 当用户点击网站页面上的内容URL，经过本地DNS系统解析

How to setup a rewrite rule on Azure CDN to serve index.html that don't match a path pattern?

由 ＊爱你＆永不变心＊ 提交于 2019-12-14 02:14:48
问题 I want to use Azure CDN (which is powered by EdgeCast, apparently) to serve static content for my React + GraphQL web app. The CDN will pull the static files from a Storage account, and Node.js will handle the GraphQL endpoint. For the client-side routing to work properly, I need to serve /static/index.html for all requests that don't match the static content path ( /static/somefile.ext ). I want to avoid using Node.js to serve the index.html in this fashion: var express = require('express');
