Frequently Asked Questions

Common questions about Headers Security Advanced & HSTS WP

No. Headers add less than 1KB to each response. The plugin uses WordPress native hooks and adds no database queries at page load for visitors.

Yes. On Apache and LiteSpeed the plugin writes the headers to .htaccess so the web server applies them to every response, including cached HTML and static files, and PHP does not emit a duplicate. On Nginx and IIS (which do not read .htaccess) the headers are sent via PHP, so your normal pages are covered; if you run a server-level cache there, add the equivalent rules to the server config (the plugin's Settings page shows the exact snippet).

Yes. On Apache and LiteSpeed the headers are served at the web-server layer (.htaccess), so they are present even on fully cached pages and on static files that never invoke PHP - including caches that serve static HTML through mod_rewrite: W3 Total Cache (including Disk: Enhanced), WP Super Cache (both "Simple" and "Expert"/mod_rewrite modes), Cache Enabler and WP Fastest Cache. On Nginx and IIS those .htaccess rewrite rules are not read, so a server-level cache that serves HTML without PHP needs the equivalent headers added to the server config by your host; pages served through PHP are covered as usual. Note on WP Rocket: it serves its cache through an early advanced-cache.php drop-in that runs before plugins load, so we do not yet claim coverage for its cached responses on any stack - we have modelled this but not verified it on a live WP Rocket site. If you use WP Rocket, check the cached responses with your browser's network tab and, if a header is missing, add the equivalent rule at the server or CDN level.

Yes. Cloudflare passes through headers set by WordPress. If you also set the same headers in the Cloudflare dashboard, open Settings → "Advanced: per-header delivery" and set the matching header to "Off" to avoid duplicates.

Your site needs all 6 scored headers present: Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and Permissions-Policy. The plugin configures all of these automatically.

Rarely. The plugin detects and resolves its own duplicates automatically. If another plugin or your server sets the same header and a duplicate remains, open Settings → "Advanced: per-header delivery" and set that header to "Server only" (keep the server copy, drop the plugin copy) or "Off".

HTTP Strict Transport Security tells browsers to always use HTTPS. Even if someone types http://, the browser upgrades to https:// automatically. Prevents protocol downgrade attacks.

Minimum for preload: 31536000 (1 year). Recommended: 63072000 (2 years). Start with 86400 (1 day) to test, then increase.

Only if your entire domain (including all subdomains) works over HTTPS. Preload is hardcoded in browsers and difficult to undo. Removal takes months. Test thoroughly first.

CSP tells browsers which resources can load on your page. Anything not explicitly allowed is blocked. It is the strongest protection against XSS attacks.
