The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded.
When the site's visitors attempt to connect to the site, this response is included ("stapled") with the TLS/SSL handshake via the Certificate Status Request extension response (note: the TLS client must explicitly include a Certificate Status Request extension in its ClientHello TLS/SSL handshake message).

The browser sends the certificate's serial number to the certificate authority or its delegate via OCSP (Online Certificate Status Protocol) and the authority responds, telling the browser whether the certificate is still valid or not. [35] The CA may also issue a CRL to tell people that these certificates are revoked.
This reversible status can be used to note the temporary invalidity of the certificate (e.g., if the user is unsure if the private key has been lost). If, in this example, the private key was found and nobody had access to it, the status could be reinstated, and the certificate is valid again, thus removing the certificate from future CRLs.
The Online Certificate Status Protocol (OCSP) allows clients to interactively ask a server (an OCSP responder) about a certificate's status, receiving a response that is cryptographically authenticated by the issuing CA. [29] It was designed to address issues with CRLs. [30] A typical OCSP response is less than 1 kB. [31]
