backends.http.idle-timeout

idle_timeout

Set how long an HTTP backend keeps an unused connection open for reuse. This backend-level setting applies to both a single url and named server endpoints.

backends {
    http "API" {
        url "https://api.example.com";
        idle_timeout 30s;
        get "LOOKUP" { path "/users"; }
    }
}

Default: 90s.

Use a nonnegative duration, such as 500ms, 30s, or 2m. Plain numbers use milliseconds. Set 0s to disable idle connection reuse.

After a connection has been unused for this duration, Radiator Server closes it. A later request opens a new connection if needed. Requests in progress are unaffected. The backend service can close a connection sooner.

Use timeout to limit each request attempt. Use connections to limit concurrent operations.
