Setup push invalidation for Cloudflare
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 |
cloudflare |
|
cdn.prod.plan |
e.g. free |
values: default: only enterprise plan supports purge-by-tag |
cdn.prod.zoneId |
<Cloudflare Zone ID> |
ID of production zone |
cdn.prod.apiToken |
<Cloudflare API Token> |
To create an API Token,
- go to API Tokens
- click on "Create Token",
- go to "Create Custom Token" at the bottom and click on "Get started"
- enter a token name (e.g.
"Production Site Purge Token"), - Permissions: "Zone", "Cache Purge", "Purge"
- Zone Resources: "Include", "Specific zone", "<your production zone>"
- click on "Continue to summary"
- click on "Create Token",
- copy the generated token value.
Note that only sites on the enterprise plan will be surgically purged by url and cache key. A Purge All will be performed instead on non-enterprise sites every time an author publishes a content change.
You can validate the credentials with this tool.
