RenderingResponse does not set status code on redirect views

[tgrushka]

Version: org.springframework:spring-webflux:5.3.21

Problem: When I use RenderingResponse.create("redirect:/controller").status(HttpStatus.FOUND).build(), the response status is not modified (remains 303 See Other no matter what).

(.status(something) works fine on a non-redirect view: RenderingResponse.create("template").status(something).build().)

Expected Behavior: When I modify the status of a "redirect view", I expect the status to be as directed in the invocation.

Actual Behavior: The redirect works fine. However, its status is 303 See Other no matter what I set it to.

I have a router:

@Configuration
class CVRouter(private val controller: CVController) {
    @Bean
    fun route() = router {
        path("/cvs").nest {
            GET("", controller::list)
            GET("new", controller::new)
            POST("", controller::create)
        }
    }
}

and a controller:

@Component
class CVController(val repository: CVRepository) {
    fun list(request: ServerRequest) = RenderingResponse
        .create("cv/list")
        .modelAttribute("cvs", repository.findAll())
        .build()

    fun new(request: ServerRequest) = RenderingResponse
        .create("cv/new")
        .modelAttribute("cv", CV(name = "Test Name"))
        .build()

    // This does not create anything yet, only testing PRG (Post/Redirect/Get) pattern.
    fun create(request: ServerRequest) = RenderingResponse
        .create("redirect:/cvs")
        .status(HttpStatus.FOUND)
        .build()
}
