CDN Product Description

A content delivery network (hereinafter CDN) consists of a number of nodes (caching servers), thanks to which the distribution of static content is accelerated. The network of caching servers allows solving problems related to the quality and speed of content delivery to geographically distributed users, including reducing the load on the main servers of web projects.

The product supports user types and roles.

How it works⁠

The file at the first user request is loaded into the cache of CDN-servers from the main server — the source of content. On subsequent requests for the same file, it is given from the caching CDN servers.

CDN servers do not store data permanently, but cache it for a period of time that depends on how often that data is accessed.

If there are no requests for files for a long period of time, the files are automatically deleted from the caching server. When the user makes a new request, the file is downloaded again from the main server.

Cached files are updated depending on the cache settings. The default cache lifetime is 24 hours: once every 24 hours, the CDN will contact the source and check if the original files have changed. If the files have changed, the CDN will update them by downloading them from the primary server.
