can be easily copied through CDN. Websites usually use third-party CDN. For example, Facebook's static files are hosted by Akamai, the largest CDN provider. For example, when you try to ping static.ak.fbcdn.net, you may obtain a response from an akamai.net server. Interestingly, when you ping the server again, the response server may be different. This shows that the load balancing function starts to take effect.10. The browser sends an asynchronous

It is now available on all devices. Instead of providing your static image developers with fully functional HTML and CSS code.Screenqueri. es Screenqueri. es is a pixel perfect response design test tool that allows you to test your response design on 30 different devices with resolutions preset or checke

communication and transmission solution. You can set up multiple servers in the access interval and use global Load Balancing Devices, such as radware's Web Server pilot to optimize routes so that users can access nearby sites. You can also use CDN, for example, the Akamai or solidspeed solution places a large number of dynamic page objects, images and PDF files in a buffer close to the user, so that users can access the website content nearby.

response may contain the etag header (the object Value of the requested variable) that works like the version number. If the browser observes that the file version etag already exists, stop the transfer of this file immediately. Try to guess"Fbcdn.net"What does the address represent? The smart answer is "Facebook content delivery network ". Facebook uses the content delivery network (CDN) to distribute static files such as images, CSS tables, and JavaScript files. Therefore, these files will be

collected on this site for you. It not only has video players applied on the website, but also has plug-ins tailored for WordPress fans, if you are looking for such resources, let's take a look.1. flowplayer Flowplayer is an open-source (GPL 3) video player on the network. It is used to embed video streams into your web page. Designed for website owners, developers, enthusiasts, enterprises and serious programmers. With flowplayer, you can customize your own player and put it on your website to

content often represents the bandwidth size of the site and can be easily replicated through a CDN. A third-party CDN is usually used by the website. For example, Facebook's static files are hosted by Akamai, the largest CDN provider.For example, you might get a response from a akamai.net server when you try to ping static.ak.fbcdn.net. Interestingly, when you ping again, the server may be different, which means that the load balance behind the scene

to shorten the distance between users and content servers.Keep in mind that 80% to 90% of the response time in the end user's response time is used to download images, stylesheets, scripts, Flash, and other page content. This is the Golden Code of website performance. It would be a little better to distribute static content first, than to redesign your application architecture for a more difficult task. This not only shortens response times, but it is easier to implement for content distributio

Recently, Google and Firefox have blocked most of the domestic CA institutions, resulting in the use of the domestic CA method of the certificate in the Chrome browser display as unsafe sites, foreign certificates are more expensive, found an open source free Certificate Authority Let's encrypt,By the Mozilla, Cisco, Akamai, Identrust, eff and other organizations to initiate, more authoritative, the following example is NginxThe deployment installatio

So as to lead the Chinese CDN industry growth space and growth rate. Thus, based on 2014 annual revenue, the 2015 blue Flood ChinaCache CDN Business will easily exceed 1.5 b

. header compression. the header of the http1.x mentioned above is often repeated superfluous. Choosing the appropriate compression algorithm can reduce the size and number of packets. The transmission of encryption protocol based on HTTPS greatly improves the reliability of transmission data. service-side push (server push), using the Spdy Web page, For example, my Web page has a SYTLE.CSS request, while the client receives SYTLE.CSS data, the server pushes the Sytle.js file to the

Typically, HTTP requests from the browser are filled in by a CDN or other caching technology, which avoids the performance discount that comes with the backend Web server at all times. This approach is designed to provide better performance for static content such as images. For example, Akamai (Network acces

vendors have to face the problem of communication and routing, to make a website to "close" users, we have to work on communication transmission programs. You can set up multiple servers in the access interval and use global load balancing devices, such as the Radware Company's Web server guide, to optimize routing so that users can access the nearest site, or you can use CDN, such as Akamai or solidspeed schemes, by moving a large number of dynamic

different regions. But as you can see, the pages in these countries are a little bit abnormally low. Cucumbertown is an asset-heavy web site, and although we postponed all the action on Requiejs and then actively loaded JavaScript on demand, we made a lot of effort to load the underlying script. We have confirmed that Cucumbertown's loading time in the United States is 2.5 seconds, compared to other countries this is simply the speed of light, DSL equipment around the world a week delay is 43

servers or arrays to the Internet are considered "upstream", those farthest considered "downstream"). This allows the cached content to be as close to the user as it needs it. Arrays are highly scalable because you can add servers to the array or increase the array level to a hierarchical architecture without disrupting the current caching solution. Another scalability issue is the ability to use caching to reduce network bandwidth for branch offices. The branch office agent may not be connec

tutorial channel Some large web companies have their own CDN, but the cost of using CDN services like Akamai Technologies, Mirror image Internet, or limelight Networks is very high. For start-ups and personal sites, it may not be possible to use CDN's cost budget, but as the target user base expands and becomes more globalized, CDN is required to achieve fast response. In the case of Yahoo, the static content of the website program they transferred

allows you to specify an HTTP GET or http POST parameter to change the cache entry. For example, just set the varybyparam= "a" to default.aspx? Report=1 or default.aspx? report=2 for output caching. You can also specify additional parameters by specifying a semicolon-delimited list.Many people don't know when to use output caching, and the ASP.net page also generates some HTTP headers downstream of the cache server, such as the headers used by Microsoft Internet Security and Acceleration Server
