i'm trying to get image caching working with Ktor but it doesn't seem to do anything, what am i missing?

install(CachingHeaders) {
        options { outgoingContent ->
            when (outgoingContent.contentType?.withoutParameters()) {
                ContentType.Image.Any -> CachingOptions(CacheControl.MaxAge(maxAgeSeconds = 30 * 24 * 60 * 60))
                else -> null
            }
        }
    }

routing {
    ...
    static("/img/") {
            resources("/static/img/")
            ...
    }
}
