Systems and methods for flash crowd control and batching OCSP requests via online certificate status protocol

摘要

The present invention is directed towards systems and methods for batching OCSP requests and caching corresponding responses. An intermediary between a plurality of clients and one or more servers receives a first client certificate during a first SSL handshake with a first client and a second client certificate during a second SSL handshake with a second client. The intermediary may identify that the statuses of the client certificates are not in a cache of the intermediary. An OCSP responder of the intermediary may transmit a single request to an OCSP server to determine the statuses. The intermediary may determine, from a single response received from the OCSP server, whether to establish SSL connections with the clients based on the statuses. The intermediary may store the statuses to the cache for determining whether to establish a SSL connection in response to receiving a client certificate from the first client.
