I have anumber HttpClient instances that I want to apply outgoing header CallId for and I would like avoid setting it everywhere. I have tried extending it like:

suspend inline fun HttpClient.get(url: String): HttpResponse {
        return get(url) {
            headers {
                append(HttpHeaders.XRequestId, MDC.get("CallId"))
            }
        }
    }

But that does not allow for setting other headers that are needed in only a few places.
Is there a way to always set a particular header like this one which is per request but still allow for more customization of the headers or other properties in specific call sites?

The DefaultRequest plugin should help.

Thanks that looks precisely like what I would need!
