Authority Information Access

The authority information access (AIA) extension contains the URLs at which the issuing CA's certificate is published. The client uses these URLs when creating a certificate chain to retrieve the CA certificate if it does not have a copy of this certificate in a copy of the client cache . Modify the AIA extension to an alternate location if you want to take the CA offline. You must also export the CA certificate and place it in this alternate location to support certificate chain requests. The AIA also contains the URL of any online responders that you have configured to support revocation checks . You learn more about online responders later in this lesson.
