OCSP Stapling (Certificate Revocation)
Checks if the web server pre-fetches and caches SSL revocation status to optimize connection speed and user privacy.
Why It Matters
Without OCSP stapling, the browser must query the CA directly on every visit, adding 100ms+ latency and leaking browsing data.
How We Check This
We request OCSP status (status_request) during the TLS handshake and check for a signed OCSP response.
How to Fix & Implement
Copy-paste configuration blocks tailored for your web server or edge proxy.
