2.1.1.2.2 License Retrieval

When license retrieval is implemented using HTTP, the rules that are specified in section 2.1.1.3.1 MUST be followed.

When transferring content that is encapsulated in ASF using HTTP, a standard license is delivered to the receiver; however, for any other content type, a root license is sent to the receiver. The leaf licenses that chain to the root license are delivered in control frames during the license update procedure, as specified in section 2.1.1.2.1.
