CDNs work by storing cached copies of a websites static content, such as images, CSS files, and JavaScript files, on multiple servers located in various data centers. When a user accesses a website, the CDN will determine the users location and serve content from the nearest server, reducing latency and improving loading times.How Does a CDN Work?When a user requests access to a website, the request is routed to the nearest CDN server, known as the edge server. The edge server delivers the cached content to the user quickly and efficiently, thereby reducing the load on the origin server and improving overall website performance. CDNs also utilize techniques such as TCP optimization, caching, and content compression to further enhance speed and reliability.Benefits of Using a CDNThere are several benefits to using a CDN for your website1.
