However, those lists may be large and need to be + updated frequently in order to remain current and thus useful.</p> + +<p>The preferred way to combat the threat of compromised certificates is to use + a special server that supports the Online Certificate Status Protocol (OCSP). + Such a server can answer client queries about individual certificates (see + <a href="#configuring_ocsp">Configuring OCSP</a>, below).</p> + +<p>The server, called an OCSP responder, receives an updated CRL periodically + from the CA that issues the certificates to be verified.
