Overview

Header keys SHOULD be allocated to one of the four defined header names based upon their expected level of variability:

• CMCD-Object: keys whose values vary with the object being requested.
• CMCD-Request: keys whose values vary with each request.
• CMCD-Session: keys whose values are expected to be invariant over the life of the session.
• CMCD-Status: keys whose values do not vary with every request or object.
