How are the CDN images uploaded?

  • Hi,
    I enabled CDN for one of our sites and I’m curious to know how can WP Super Cache upload the files (images, css, js) to CDN? In other words, I would like to know how the files (including the ones from the future posts / pages) are sent to the CDN (as while activating the CDN, it didn’t ask for AWS Cloudfront credentials / keys)?

    I use Amazon Cloudfront.

  • The files will be automatically fetched from your origin server, that’s why CDN login credentials are not needed in WP SuperCache. This is called “pull”, where the CDN knows your origin server and caches them on demand.
    Here’s how a CDN works.
