Reverse Proxy

A reverse proxy is a server architecture that receives requests from clients and forwards them to one or more backend servers. Unlike a forward proxy (which represents clients), a reverse proxy operates on behalf of the server side.

Key advantages of reverse proxies:

Load Balancing: Distributes requests across multiple servers
Enhanced Security: Conceals real server information
Content Caching: Improves performance
Path Rewriting and Forwarding: Flexibly routes requests

The Salvo framework provides middleware with reverse proxy functionality.

Example Code

use salvo::prelude::*;
use salvo::proxy::Proxy;

#[tokio::main]
async fn main() {
    tracing_subscriber::fmt().init();
    
    let router = Router::new()
        .push(
            Router::new()
                .path("google/{**rest}")
                .handle(Proxy::<Vec<&str>>::new(vec!["https://www.google.com"])),
        )
        .push(
            Router::new()
                .path("baidu/{**rest}")
                .handle(Proxy::<Vec<&str>>::new(vec!["https://www.baidu.com"])),
        );
    let acceptor = TcpListener::new("127.0.0.1:5800").bind().await; Server::new(acceptor).serve(router).await;
}
