ICertRequestD::Ping and ICertRequestD2::Ping2 Request Processing

A client invokes either the ICertRequestD::Ping or ICertRequestD2::Ping2 method to determine whether the CA can be contacted.

To invoke one of these methods, use the following parameter:

pwszAuthority (see section If the client knows any one of the CA names (common name, sanitized name, or short name) it SHOULD pass it in this parameter. If the client does not know any of the CA names, it MAY pass a NULL string for this parameter.

Both the ICertRequestD::Ping and ICertRequestD2::Ping2 methods have the same meaning and use. The only difference between the methods is that Ping is a member of the ICertRequestD interface, and Ping2 is a member of the ICertRequestD2 interface.
