Since jQuery 1.3, I have not provided the pack version, and I am in favor of using Google CDN for code hosting. This solution has the following benefits: 1. Smaller downloads. We all know that there are as many as 38 kb after jQuery 1.3 pack. If you can delete the copyright annotation to get a smaller code, unfortunately this is not only shameless but only saves 1 kb. However, the Min version that uses GZip provided by Google APIs is only 18 KB, And t

Chapter 3rd DNS for setting up domain names We'll warm up before the play starts. Intelligent DNS can be said to be the basis of CDN. Believe that everyone do the site will have the following situation: Home page two links, telecommunications users please visit the main site A, Netcom users please visit the Mirror site B. Then do two domain names, www.naizhao.com point to a,cnc.naizhao.com point B. The user looked at half a day feel dizzy, casually p

Many webmaster in the process of building a large web site, often encounter the site in a specific area to open the problem of slow speed. This is usually done in that area to do a site image, through smart DNS to determine the user access to which mirror server. Here we use WDCP and WDCDN to build our CDN acceleration point. Because WDCDN relies on WDCP, we first install WDCP.The specific steps are as follows: First step: Install WDCP 1.X wget

This article is from the "practice test truth" blog How to use BIND, GeoIP, Nginx, and Varnish to create your own efficient CDN network?CDN stands for Content Distrubtion Network, which is a Content delivery Network.

Preface Recent work encountered a demand, is to filter some data according to the CDN log, such as traffic, status code statistics, TOP IP, URL, UA, Referer and so on. Used to be the bash shell implementation, but the log volume is large, the number of logs of G, the number of rows up to billies level, through the shell processing a little bit, processing time is too long. The use of the data Processing library for the next Python pandas was studied

Squid reverse proxy CDN build configuration Because of the company's business needs, you need to build a cdn node somewhere by yourself. You can build a node by using DNSpod smart resolution and squid. Installation path:/usr/local/squid 1.
