[][src]Enum rocket::http::hyper::header::Pragma

pub enum Pragma {
    NoCache,
    Ext(String),
}

The Pragma header defined by HTTP/1.0.

The "Pragma" header field allows backwards compatibility with HTTP/1.0 caches, so that clients can specify a "no-cache" request that they will understand (as Cache-Control was not defined until HTTP/1.1). When the Cache-Control header field is also present and understood in a request, Pragma is ignored. In HTTP/1.0, Pragma was defined as an extensible field for implementation-specified directives for recipients. This specification deprecates such extensions to improve interoperability.

Spec: https://tools.ietf.org/html/rfc7234#section-5.4

Examples

use hyper::header::{Headers, Pragma};

let mut headers = Headers::new();
headers.set(Pragma::NoCache);
use hyper::header::{Headers, Pragma};

let mut headers = Headers::new();
headers.set(Pragma::Ext("foobar".to_owned()));

Variants

NoCache

Corresponds to the no-cache value.

Ext(String)

Every value other than no-cache.
