How to add Cache Control to the response header of “actix_files” ？

[154286]

 App::new()
            .app_data(json_config)
            .service(actix_files::Files::new("/images", &CONFIG.images.dir).use_last_modified(true))
            .wrap(middleware::DefaultHeaders::new().add(("Cache-Control", "no-cache")))

This can achieve my goal, but it will result in all interfaces carrying this header
How can I only add Cache Control to the/images route without affecting other interfaces？

Methods like

 .service(actix_files::Files::new("/images", &CONFIG.images.dir).use_last_modified(true).wrap(middleware::DefaultHeaders::new().add(("Cache-Control", "no-cache"))))

are not feasible

Here's what I'd recommend:

.service(
    actix_web::web::scope("/images")
        .default_service(
            actix_files::Files::new("", &CONFIG.images.dir).use_last_modified(true),
        )
        .wrap(DefaultHeaders::new()...),
)

It does feel natural to want to wrap the files service like this though, I should have a think about making it easier.
