188.8.131.52 Mixed Proxy to Server Traffic
RPC over HTTP v1 uses TCP/IP between the mixed proxy and the server. The TCP connection MUST be initiated by the mixed proxy. The server name and port to be used for setting up the TCP connection MUST be extracted from the URI of the HTTP request as specified in section 184.108.40.206. Once the connection is established, the mixed proxy and the server MUST use this connection for transmission of all the PDUs in the PDU stream.
