1.5.3 Prerequisites/Preconditions for HTTP Transport

The RDGHTTP Protocol requires RDG clients to support HTTP version 1.1. When an RDG client supports only HTTP version 1.0, some features available in HTTP version 1.1 cannot be used. For example, when the chunked transfer encoding feature in HTTP version 1.1 cannot be used, the content-length field in the HTTP 1.0 header is used instead.
