https://github.com/nats-io/nats.go/blob/main/nats.go#L4063
https://github.com/nats-io/nats.go/blob/main/nats.go#L3952

what i expect: if i pass nats.Msg - use all of it not some parts.

Request function mean specifically that we handle the replies and process the reply message, those functions can’t use the supplied reply subject.

You should use PublishMsg() to send it un modified.

thats kind of "problem" that i need to copy/paste logic from "https://github.com/nats-io/nats.go/blob/main/nats.go#L4063" instead of set for msg.replyto = my.specific.inbox
because publishmsg does that? but requestmsg doesnt?

[ripienaar]

Inboxes should really be unique per request unless you do something special - in which case our logic wouldnt really work.

So what you should consider is setting a custom inbox prefix so it'll get my.specific.inbox.>

i had trie to pass inbox prefix to https://github.com/nats-io/nats.go/blob/main/nats.go#L3986 but it will be override by https://github.com/nats-io/nats.go/blob/main/nats.go#L4063 through this https://github.com/nats-io/nats.go/blob/main/nats.go#L4020

You set

nats.go/nats.go

func CustomInboxPrefix(p string) Option {

when creating the nc and all request-reply will use that prefix for the life of the nc
