Purge and Prefetch

Purge and Prefetch are functions, which allow you to manage the content which is being served through our CDN. Prefetch (sometimes called push) helps you upload your content to our edge servers, whereas purge deletes selected files from the edge servers.



Pre-populating files can be extremely useful, mainly if those files are large. Thanks to prefetching, your users will download content directly from us. You will therefore significantly increase your hit/loss ratio and increase their user experience.

Instant Purge

Deleting files can come in handy for instance if there is some cached content on our servers that you want to get rid of completely. You can also delete all the content currently cached with us, by hitting the "Purge all" button. Individual purges are cleared within seconds.


Best of all - you can automate both prefetching and purging of files. Thanks to our powerful API, you can optimize the management of your data. Prefetch files such as new software packages or videos with the use of the API.

CDN77 helps us deliver enormous quantities of Ultra HD videos as well as images of cosmos in up to gigapixel-class. What I appreciate is good personal support, good analytics, and good service with the actual CDN. I feel it is a partnership rather than a pure business relation.
