Product compatibility
As a general rule, settings on the customer zone will override settings on the SaaS zone. In addition, Orange-to-Orange does not permit traffic directed to a custom hostname zone into another custom hostname zone.
The following table provides a list of compatibility guidelines for various Cloudflare products and features.
| Product | Customer zone | SaaS provider zone | Notes |
|---|---|---|---|
| Access | Yes | Yes | |
| API Shield | Yes | No | |
| Argo Smart Routing | No | Yes | Customer zones can still use Smart Routing for non-O2O traffic. |
| Bot Management | Yes | Yes | |
| Browser Integrity Check | Yes | Yes | |
| Cache | Yes* | Yes | Though caching is possible on a customer zone, it is generally discouraged (especially for HTML). Your SaaS provider likely performs its own caching outside of Cloudflare and caching on your zone might lead to out-of-sync or stale cache states. Customer zones can still cache content that are not routed through a SaaS provider's zone. |
| China Network | No | No | |
| DNS | Yes* | Yes | As a SaaS customer, do not remove the records related to your Cloudflare for SaaS setup. Otherwise, your traffic will begin routing away from your SaaS provider. |
| HTTP/2 prioritization ↗ | Yes | Yes* | This feature must be enabled on the customer zone to function. |
| Image resizing | Yes | Yes | |
| IPv6 | Yes | Yes | |
| IPv6 Compatibility | Yes | Yes* | If the customer zone has IPv6 Compatibility enabled, generally the SaaS zone should as well. If not, make sure the SaaS zone enables Pseudo IPv4. |
| Load Balancing | No | Yes | Customer zones can still use Load Balancing for non-O2O traffic. |
| Page Rules | Yes* | Yes | Page Rules that match the subdomain used for O2O may block or interfere with the flow of visitors to your website. |
| Mirage | Yes | Yes | |
| Origin Rules | Yes | Yes | Enterprise zones can configure Origin Rules, by setting the Host Header and DNS Overrides to direct traffic to a SaaS zone. |
| Polish | Yes* | Yes | Polish only runs on cached assets. If the customer zone is bypassing cache for SaaS zone destined traffic, then images optimized by Polish will not be loaded from origin. |
| Rate Limiting | Yes* | Yes | Rate Limiting rules that match the subdomain used for O2O may block or interfere with the flow of visitors to your website. |
| Rocket Loader | No | No | |
| Security Level | Yes | Yes | |
| Spectrum | No | No | |
| Transform Rules | Yes* | Yes | Transform Rules that match the subdomain used for O2O may block or interfere with the flow of visitors to your website. |
| WAF custom rules | Yes | Yes | WAF custom rules that match the subdomain used for O2O may block or interfere with the flow of visitors to your website. |
| WAF managed rules | Yes | Yes | |
| Waiting Room | Yes | Yes | |
| Websockets | No | No | |
| Workers | Yes* | Yes | Similar to Page Rules, Workers that match the subdomain used for O2O may block or interfere with the flow of visitors to your website. |
| Zaraz | Yes | No |
