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. Carol's OCSP responder confirms that Alice's certificate is still OK, and returns a signed, successful 'OCSP response' to Bob.
OCSP stapling is designed to reduce the cost of an OCSP validation, both for the client and the OCSP responder, especially for large sites serving many simultaneous users. However, OCSP stapling supports only one OCSP response at a time, which is insufficient for certificate chains with intermediate CA certs. [26] [27]

L.A. had the option to attempt a free kick after the fair catch. It was the rare instance in which it made sense because no time remained on the clock.
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]
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web.
