OCSP stapling decreases the load on a PKI infrastructure's OCSP server by attaching a signed OCSP response to the target in a TLS connection. In addition it creates a more secure/private session since the CA doesn't know that your browser is accessing a given site. Some people have compared this behavior to Kerberos.
What web browsers support OCSP stapling?
Are there any implementation considerations among different browsers that need to be addressed to maintain uniform privacy and performance benefits?
