Is there no way to access the pipeline context within the new

on

functions in plugins? Do I simply not have to call

finish

and

proceed

anymore? Will ktor automatically detect that the request has already received a response and not pass it further down the pipeline?

Those details are hidden on purpose so there is no way.

Most of Ktor standard plugins like

Routing

work only if a response isn’t already sent so you can rewrite your code in the following way:

val plugin = createApplicationPlugin("plugin") {
    onCall { call ->
        if (!rate.check()) {
            call.respond(HttpStatusCode.TooManyRequests)
        }
    }
}

That way the execution of pipeline isn’t finished.
