Content Delivery Networks Speeding Up the Web A Content Delivery Network, or CDN, speeds up the web by moving copies of your files closer to people who visit your site. When a user in Tokyo requests a page, the CDN tries to serve images, scripts, and styles from a nearby server instead of pulling everything from your origin in a far place. This shortens travel time, reduces the chance of a traffic jam, and helps pages load faster for everyone. ...
Content Delivery Networks: Speeding Up the Web Content Delivery Networks, or CDNs, are groups of servers placed around the world. Their goal is simple: serve content from a nearby location to the user, so pages load faster. This helps especially with images, video, styles, and scripts. How a CDN works Edge servers keep copies of files. When a browser asks for a file, the CDN routes the request to the closest edge server. If the file is cached there, the edge responds quickly. If not, the edge fetches it from your origin server and saves a copy for the next visitor. Cache rules tell the edge how long to keep the file before asking again. A good TTL for static assets means fast loads, but you can still refresh content with cache purges. Some CDNs also serve content using secure connections and support modern protocols like HTTP/2 or HTTP/3 to speed up handshakes. ...
Content Delivery Networks for Global Reach A content delivery network (CDN) places copies of your files on servers around the world, so a user in Paris or Mumbai loads a page from a nearby edge server rather than a distant data center. This proximity lowers latency and helps pages feel fast, even for users far away. The core idea is caching and routing. When a user requests a file, the CDN serves it from the closest edge node. If the asset isn’t cached yet, the network fetches it from your origin and stores a copy for future requests. ...
Content Delivery Networks: Speeding Up the Web A content delivery network (CDN) is a group of servers distributed around the world. When a user asks for a page or an asset, the CDN serves it from a nearby edge server instead of the origin. This shortens the travel distance and reduces delay, which makes sites feel faster. How CDNs work CDNs place many servers in different regions. When a user requests a file, the CDN routes the request to the closest edge location. Static assets like images, CSS, and JavaScript are cached at the edge, so repeated visits load quickly. If the content isn’t in cache or has expired, the edge fetches it from the origin. ...
