Overview

  • We have covered what is CDN and how it works in Working with CDN Part – 1. In this article we will see how to configure CDN, CDN providers and etc.
  • As we have discussed, CDN caches the static content from the origin server and delivers the content to the user. When a user requests the webpage that is part of CDN server, CDN will redirect the request from origin server to CDN server that is closest to the user’s geographic location and deliver the cached content.

How to Setup CDN?

  • The first step in CDN setup is to choose a CDN provider. There are several CDN providers like CloudFlare, Amazon CloudFront, MaxCDN and etc.
  • CDN services are both paid and free. It is up to you which service will be suitable to your needs.
  • There are several ways to implement CDN in your website like you can choose a CDN provider and configure it between your web host and your CDN provider. Or you can select a web host that provides CDN service default in their configuration.
  • Here we will see how to configure a free CDN in Cloudflare. Cloudflare is the most popular free CDN provider. It is a large network of distributed servers which caches the static content and delivers the content.
  • When you connect your website to Cloudflare, it will store your files to it’s server which is known as Caching. When a user requests to access your website, Cloudflare responds to that request from it’s server to the closest location of the user.

How to Enable Cloudflare CDN in your website?

To enable Cloudflare CDN, there are two easy ways as below:

  1. Using the Cloudflare setting option in your host’s control panel.
  2. Using Cloudflare dashboard

Method-1 Using the Cloudflare setting option in your host’s control panel

  • In this method, you can select a specific web host that provides a free Cloudflare CDN option. It is just a single-click setup.
  • In your web host control panel, there is an option for Cloudflare setting, you just need to connect to your Cloudflare account and it will process activation of CDN in your website.
  • After that you need to configure your CDN settings.
