Pull Zone Configuration

Configure your Pull Zone settings for optimal performance.

Origin Settings

Origin URL

The base URL of your origin server. All requests to the CDN will be proxied to this URL.

https://example.com

Origin Host Header

The Host header sent to your origin server. Defaults to the hostname from your origin URL, but can be customized if your origin requires a specific host header.

Caching Settings

Cache TTL

Default time-to-live for cached content in seconds. This applies when your origin doesn't send cache headers.

Value Duration
3600 1 hour (default)
86400 1 day
604800 1 week
2592000 30 days

Query String Caching

Controls how query strings affect caching:

  • Enabled - URLs with different query strings are cached separately
  • Disabled - Query strings are ignored; ?v=1 and ?v=2 serve the same cached file

Enable this for versioned assets: style.css?v=123

Security Settings

CORS Headers

Enable CORS (Cross-Origin Resource Sharing) to allow your assets to be loaded from other domains.

When enabled, adds these headers:

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, HEAD, OPTIONS
Access-Control-Allow-Headers: *

Hotlink Protection

Prevent other websites from embedding your content. See Hotlink Protection for details.

WAF (Firewall)

Block traffic by IP address or country. See WAF Documentation for details.

Optimization Settings

Image Optimization

Automatically optimize images for faster delivery:

  • WebP conversion for supported browsers
  • Quality adjustment
  • On-the-fly resizing

See Image Optimization for details.

Minification

Minify CSS and JavaScript files to reduce file size:

  • Remove whitespace and comments
  • Shorten variable names (JS)
  • Combine selectors (CSS)

See Minification for details.

Script Injection

Inject custom scripts into HTML responses:

  • Analytics tracking
  • Chat widgets
  • A/B testing scripts

See Script Injection for details.

Advanced Settings

Error Page Caching

By default, error responses (4xx, 5xx) are not cached. Contact support if you need custom error caching behavior.

Origin Timeout

The maximum time to wait for a response from your origin. Default: 30 seconds.

Follow Redirects

By default, redirects from your origin are passed through to the client. The CDN does not follow redirects internally.
