2.1.2 RPC over HTTP v2 Transport

The following sections define the mapping of the RPC over HTTP v2 protocol dialect over lower-layer protocols. From a high-level perspective, in its steady state this protocol uses a pair of custom HTTP requests from the client to the inbound proxy and from the client to the outbound proxy. All inbound RPC PDUs are mapped as BLOBs in the message body of the custom request to the inbound proxy, and all outbound RPC PDUs are mapped as BLOBs in the message body of the custom request to the outbound proxy.
