Setup push invalidation for Fastly
Push invalidation automatically purges content on the customer's production CDN (e.g. www.yourdomain.com), whenever an author publishes content changes.
Content is purged by url and by cache tag/key.
Push invalidation is enabled by adding specific properties to the project's configuration (an Excel workbook named .helix/config.xlsx in Sharepoint or a Google Sheet named .helix/config in Google Drive).
Configuration properties:
| key | value | comment |
cdn.prod.host |
<Production Host> |
Host name of production site, e.g. www.yourdomain.com |
cdn.prod.type |
fastly |
|
cdn.prod.serviceId |
<Fastly Service ID> |
Service ID of production service |
cdn.prod.authToken |
<Fastly API Token> |
