The JSON-RPC protocol defines client and server strictly by who sends the request and who handles the response. An endpoint can be both a client and server at the same time over the same connection if the transport permits. For example, Endpoint-1 connects to Endpoint-2 using a standard TCP socket or UNIX socket. Endpoint-1 is a "JSON-RPC" client when it sends a request, and Endpoint-2 is a "JSON-RPC" server when it receives the request and sends a response. But when Endpoint-2 initiates a request to Endpoint-1 over the same connection, Endpoint-2 is a "JSON-RPC" client and Endpoint-1 is a "JSON-RPC" server (i.e. the roles have switched, which is not prohibited by the protocol). After the definition of client/server the spec says: "One implementation of this specification could easily fill both of those roles, *even at the same time*, to other different clients or the same client" _______________________________________________ fpc-pascal maillist - [email protected] https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
