Allowlisting (Whitelisting) Clickio CDN

In case your server or hosting use any firewalls, bot protection, traffic limitation, manual blocklisting (blacklisting), DoS or DDoS protection systems - Clickio servers should be added to the allowlists (whitelists) in order to be able to receive data from the site CMS without interruptions.

Clickio servers use these user-agents when sending requests to your server:

  • Clickio-Prism,
  • Clickio Amp robot.

Please make sure these user-agents are not blocked.

Clickio servers use these  IP ranges:

Also available as an IPv4 text list.

Cloudflare: bypass caching for Clickio social icons

Clickio generates social sharing icons dynamically under /cl-icon/. Icon colours depend on URL query parameters. Incorrect caching may cause icons to appear as black circles or display incorrect colours.

If your website uses Cloudflare, configure a Cache Rule to bypass caching for these requests:

  1. Open your website in the Cloudflare dashboard.
  2. Go to Caching → Cache Rules → Create rule.
  3. Name the rule Clickio social icons — bypass cache.
  4. Select Custom filter expression and configure:
    • Field: URI Path
    • Operator: starts with
    • Value: /cl-icon/

    Alternatively, use the expression editor:

    starts_with(http.request.uri.path, "/cl-icon/")
  5. Under Cache eligibility, select Bypass cache.
  6. Place this rule after any other Cache Rules that enable caching for the same path, then deploy it.
  7. Purge existing cached resources under /cl-icon/, including query-string variants.
  8. Reload the affected page with browser caching disabled and verify that the social icons display the expected colours.

Note: Use /cl-icon/ without an asterisk with the starts with operator.
