I need signals because each time I shut down my server I then have "address is already in use" for the next 2 minutes

from actix-web.

GildedHonour commented on May 4, 2024

how to turn off this 2 minutes feature, at least in the development ?

from actix-web.

fafhrd91 commented on May 4, 2024

I'll fix "address in use" later today.
for now use .keep_alive(Some(0))

let addr = HttpServer::new(|| {
        Application::new()
            .resource("/", |r| r.h(httpcodes::HTTPOk))})
        .bind("127.0.0.1:8080").unwrap()
        .keep_alive(Some(0))                     // <- add this
        .start();
