Content Delivery Network (CDN)

Cache rules



CDN cache rules



The principle of the CDN is to cache some elements of your website, as explain on this other page, in order to speed up the delivery of the content to your users, wherever they're located in the world.

Which elements are affected and by which rules?

You will find the answers to these questions in the table below:


GeoCache WebStorage InfraStructure
Cache Automatic On demand Customised
Details Any file on the associated Web Hosting system within the size limits, will automatically be registered and cached by the CDN. Any file placed in the storage space provided is replicated in 3 datacentres, in Roubaix, Strasbourg and Beauharnois. If the file is within the maximum size limits, it can be cached on the PoPs, via an operation that consists of creating a web link to this element, thus cached on the CDN. Any file on the disk space can be cached, as long as it doesn't exceed the maximum size limit. The decision to be applied to a file depends on the rules dictated by the customer in the configuration of their infrastructure AND the customised backend rules, as defined in the OVH Control Panel.
File types Any image, video, audio, CSS, or JS file Any file stored on the rented disk space Any file on the associated hosting system, server or infrastructure
File size 100 MB on European PoPs/20 MB on American - Asian PoPs*
