Middleware that provides support for cache header configuration.

In fact, the implementation contains three Handler implementations of CachingHeaders, Modified, ETag, and CachingHeaders is a combination of the latter two. Normally, CachingHeaders is used.

Sample Code

use salvo::prelude::*;

#[handler]
async fn hello_world() -> &'static str {
    "Hello World"
}

#[tokio::main]
async fn main() {
    tracing_subscriber::fmt().init();

    tracing::info!("Listening on http://127.0.0.1:7878");
    // CachingHeader must be before Compression.
    let router = Router::with_hoop(CachingHeaders::new())
        .hoop(Compression::new().with_min_length(0))
        .get(hello_world);
    Server::new(TcpListener::bind("127.0.0.1:7878")).serve(router).await;
}
