Systems and methods for evaluating and prioritizing responses from multiple OCSP responders

A system of determining by an intermediary device a status of a client certificate from a plurality of responses for an Online Certificate Status Protocol (OCSP) request, the intermediary device between a plurality of clients and one or more servers, the system comprising:

• an intermediary device identifying a plurality of Online Certificate Status Protocol (OCSP) responders executing on the intermediary device and corresponding to a certificate authority for determining a status of a client certificate responsive to receiving the client certificate from a client during a Secure Socket Layer (SSL) handshake;
• each OCSP responder of the plurality of OCSP responders transmitting a request for the status of the client certificate to a uniform resource locator corresponding to each OCSP responder, while remaining portions of the SSL handshake are performed without the status of the client certificate;
• and
• an SSL engine of the intermediary device determining a single status for the client certificate from a plurality of statuses of the client certificate received via responses from each uniform resource locator.
