Purging invalidates (removes) a cached object ahead of when it would naturally expire. You may want to purge something because it’s incorrect, out of date, or because you have a breaking update.

When used in a technological setting, the term “cookie” refers to a small text file that is stored on a user’s computer or mobile device when they visit a website.

CDNs work by distributing content across globally distributed servers, caching data at these edge locations (servers placed near end-users globally), and routing user requests to the nearest server to deliver content quickly and efficiently.

Learn how to choose a CDN that delivers the optimal content delivery, enhances user experience, and robust security your business needs to thrive.

Code operates behind the scenes and is largely invisible to users (except for web developers using inspect tools). Content, in contrast, is directly visible and forms the user's primary interaction with the site.

Making your site faster improves user experience, keeping visitors on your page for longer. Quick-loading pages also lead to higher engagement, better search engine rankings, and increased conversions.

Latency is the delay between when data is generated or requested and when it becomes available for use or processing.

A cache is a location that temporarily stores data for faster retrieval when something needs access to it. Caching refers to the process of storing this data.

Live streaming is a real-time data transmission method enabling video content to be shared and viewed simultaneously without the need for prior recording or storage.

Learn about the metrics and best practices you should consider when gauging the performance of your CDN.

Image optimization refers to the process of modifying and delivering high-quality images in the optimal format, dimension, and resolution for the device accessing them, all while keeping the smallest possible file size that will not result in noticeable image degradation.
