Async HTTP and WebSocket client library.
```rust use actix_rt::System; use awc::Client;
fn main() { System::new().block_on(async { let client = Client::default();
let res = client
.get("http://www.rust-lang.org") // <- Create request builder
.insert_header(("User-Agent", "Actix-web"))
.send() // <- Send http request
.await;
println!("Response: {:?}", res); // <- server http response
});
} ```
