How CDN Works at Pressable

Pressable Global CDN

All Pressable sites can activate our Content Delivery Network (CDN). Our CDN has points of presence (PoPs) globally, as shown on the map above. These PoPs allow us to deliver content to your site’s visitors from a server nearest them.

Pressable’s CDN caches static assets with the following file extensions: jpg, jpeg, gif, png, css, bmp, js, ico file type.

By default, the cache-control header is set to 7 days, meaning that browsers receive a directive to store the file for 7 days. This time period can be changed to 10 years.

The CDN only caches static assets. It does not cache pages, nor does it cache data from the database.

Pressable rewrites URLs pointing to the aforementioned assets on page load. The URL used is based on the following format: At this time, it is not possible to use Pressable’s CDN with a custom domain or the primary domain assigned to a site.

Enable the CDN

To activate the CDN on your site, you may visit your site settings page in MyPressable Control Panel and click “Enable” in the CDN section. The CDN cannot be used on sites without an assigned domain.
