Struct actix_web::http::header::CacheControl

pub struct CacheControl(pub Vec<CacheDirective>);

Cache-Control header, defined in RFC7234

The Cache-Control header field is used to specify directives for caches along the request/response chain. Such cache directives are unidirectional in that the presence of a directive in a request does not imply that the same directive is to be given in the response.

ABNF

Cache-Control   = 1#cache-directive
cache-directive = token [ "=" ( token / quoted-string ) ]

Example values

• no-cache
• private, community="UCI"
• max-age=30

Examples

use actix_web::HttpResponse;
use actix_web::http::header::{CacheControl, CacheDirective};

let mut builder = HttpResponse::Ok();
builder.insert_header(CacheControl(vec![CacheDirective::MaxAge(86400u32)]));

use actix_web::HttpResponse;
use actix_web::http::header::{CacheControl, CacheDirective};

let mut builder = HttpResponse::Ok();
builder.insert_header(CacheControl(vec![
    CacheDirective::NoCache,
    CacheDirective::Private,
    CacheDirective::MaxAge(360u32),
    CacheDirective::Extension("foo".to_owned(), Some("bar".to_owned())),
]));
