Expand description

If-None-Match header, defined in RFC 7232 §3.2

The If-None-Match header field makes the request method conditional on a recipient cache or origin server either not having any current representation of the target resource, when the field-value is “*”, or having a selected representation with an entity-tag that does not match any of those listed in the field-value.

A recipient MUST use the weak comparison function when comparing entity-tags for If-None-Match (Section 2.3.2), since weak entity-tags can be used for cache validation even if there have been changes to the representation data.

ABNF

If-None-Match = "*" / 1#entity-tag

Example Values

"xyzzy"
W/"xyzzy"
"xyzzy", "r2d2xxxx", "c3piozzzz"
W/"xyzzy", W/"r2d2xxxx", W/"c3piozzzz"
*

Examples

use actix_web::HttpResponse;
use actix_web::http::header::IfNoneMatch;

let mut builder = HttpResponse::Ok();
builder.insert_header(IfNoneMatch::Any);

use actix_web::HttpResponse;
use actix_web::http::header::{IfNoneMatch, EntityTag};

let mut builder = HttpResponse::Ok();
builder.insert_header(
    IfNoneMatch::Items(vec![
        EntityTag::new(false, "xyzzy".to_owned()),
        EntityTag::new(false, "foobar".to_owned()),
        EntityTag::new(false, "bazquux".to_owned()),
    ])
);
