## Streaming Requests

Streams consists of an initial request with payload and allows for full two-way communication between the client and server.

The handler function has this signature.

Sample handler:
```go
    handler :=  func(ctx context.Context, payload []byte, in <-chan []byte, out chan<- []byte) *RemoteErr {
        fmt.Println("Got request with initial payload", p, "from", GetCaller(ctx context.Context))

#         ; freeGenList = list:{ [env or config or label or message or html] }
#         ; propertiesHtmlList = list:{ [env or config or label or message] }
#     }
#     ; appMap = map:{
#         ; [application name, camel case, initial uncapitalised] = map:{
#             ; path = [relative path to application project from DBFlute client]
#             ; freeGenList = list:{ [env or config or label or message or html] }

# This file contains the initial defaults for go command configuration.
# Values set by 'go env -w' and written to the user's go/env file override these.
# The environment overrides everything else.
