What is OCSP URL?
The Online Certificate Status Protocol (OCSP) URL application definition field determines whether this application uses a general OCSP responder to send requests during certificate validation for end entity certificates. However, the other configured OCSP attributes continue to be used as appropriate. …
Why is the Online Certificate Status Protocol OCSP preferred over traditional certificate revocation lists CRL?
For time-sensitive applications, OCSP is the preferred approach. CRL checking is faster because lookup for certificate status is done on information cached on the VPN device. OCSP requires time to obtain the revocation status from an external server.
What is a limitation of using a CRL to determine if a certificate is valid?
However, there are drawbacks to both: CRL lists grow and CAs release new lists. Since CRL-based verification methods require certificate revocation status checks for every connection, there’s a chance that the CRL issuer or CA may release a new list and you’ll miss out on newly revoked certificates.
Does OCSP replace CRL?
Because the OCSP responder is queried for every certificate, whereas the CRL is downloaded periodically (for example, once per day), OCSP responses might be more up-to-date than corresponding CRLs.

How is the OCSP approach different from the CRL approach?

Can a CRL be used to revoke a certificate?
Because CRL’s contain information for lots of certificates they are often large and thus not suitable for a fast revocation check. The Online Certificate Status Protocol (OCSP) instead checks only a specific certificate and asks the OCSP responder if this certificate was revoked or not.
