Why Header and Server Checks Sometimes Disagree with Expectations
Modern WordPress hosting often includes multiple layers: the web server, reverse proxies, CDNs, security services, and hosting control panels. A header or server rule may be set in one place and altered in another.
Why Troubleshooting Matters
If a header appears missing or a server check reports an unexpected result, the issue may not be the plugin. It may be a deployment path, a proxy layer, a conditional rule, or a server-specific override.
Common Causes
- Headers added at one layer but stripped at another
- CDN behavior masking origin configuration
- Environment-specific rules between staging and production
- Server software differences affecting implementation
Why We Recommend Investigating the Full Request Path
Security checks are only as accurate as the response path they observe. Understanding that path is often the key to resolving confusing results.
