What does it do?
The pull protocol controls the protocol that the StackPath CDN uses to pull content from your origin server.
When and how should I use it?
Choose one of these options:
- HTTP or HTTPS: StackPath uses the same protocol that site visitors use to access your site.
- HTTP Only: StackPath uses unencrypted HTTP connections to communicate with your origin. Choose this if your origin does not have HTTPS configured.
- HTTPS Only: StackPath makes only HTTPS requests to your origin. Chose this to encrypt all traffic from the CDN to your origin, if your origin supports HTTPS connections.
Note: User requests for content pass through the CDN before the CDN requests content from your origin. This feature affects how the CDN communicates with your origin. We highly recommend setting up a free EdgeSSL certificate and the EdgeRules to force HTTPS connections to ensure encrypted communication between your users and the CDN.
