How to set cache-control on Files response

[danieldickison]

I apologize if this is something basic that I'm missing, but say I want to set a Cache-Control: max-age=604800 header on static actix_files::Files responses. How would I go about doing that? I see methods for toggling etag and mod_date but I'm not sure how to add extra headers to arbitrary middleware responses.

Thanks for any pointers!

I think I figured this out, which is to use web::scope for the static Files service, and adding a DefaultHeaders middleware just for that scope:

.service(
    web::scope("/static")
        .wrap(middleware::DefaultHeaders::new().add(("Cache-Control", "max-age=86400")))
        .service(Files::new("/", &config.static_path).prefer_utf8(true)),
)
