Abstract
Techniques are disclosed for locally distributing online certificate status protocol (OCSP) responses to a client computer. A certificate authority (CA) proactively sends OCSP responses to an agent application (e.g., an antivirus application configured to handle OCSP responses) residing in the client computer. The agent application stores the OCSP responses in a cache. Thereafter, when a browser application sends an OCSP request to the CA, the agent application intercepts the request and determines whether a corresponding OCSP response is locally cached. If so, the agent application sends the cached OCSP response to the browser application. If not, the agent application retrieves the corresponding OCSP response from the CA and sends the response to the browser application.
