If you set it to `--forwarded-allow-ips="*"` it would trust all the incoming IPs.

If your **server** is behind a trusted **proxy** and only the proxy talks to it, this would make it accept whatever is the IP of that **proxy**.

## Перезапуски { #restarts }

Подобно тому как вы обеспечиваете запуск приложения при старте, вы, вероятно, захотите обеспечить его **перезапуск** после сбоев.

### Мы ошибаемся { #we-make-mistakes }

Мы, люди, постоянно совершаем **ошибки**. В программном обеспечении почти всегда есть **баги**, скрытые в разных местах. 🐛

headers permit multiple values, like Guava's [Multimap](https://guava.dev/releases/23.0/api/docs/com/google/common/collect/Multimap.html). For example, it's legal and common for an HTTP response to supply multiple `Vary` headers. OkHttp's APIs attempt to make both cases comfortable.

When writing request headers, use `header(name, value)` to set the only occurrence of `name` to `value`. If there are existing values, they will be removed before the new value is added. Use `addHeader(name, value)`...
