A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

Handlers should remain backwards compatible. If a breaking API change is required, a new handler ID should be created.

## Setup & Configuration

A **Manager** is used to manage all incoming and outgoing connections to a server.

On startup all remote servers must be specified. 

* Potwierdzi, że w ścieżce jest `item_id` dla żądań `GET` i `PUT`.
* Potwierdzi, że `item_id` jest typu `int` dla żądań `GET` i `PUT`.
    * Jeżeli nie jest, odbiorca zobaczy przydatną, przejrzystą wiadomość z błędem.
* Sprawdzi czy w ścieżce jest opcjonalny parametr zapytania `q` (np. `http://127.0.0.1:8000/items/foo?q=somequery`) dla żądania `GET`.
    * Jako że parametr `q` jest zadeklarowany jako `= None`, jest on opcjonalny.

### Zrozum problem

* Najpierw upewnij się, że **rozumiesz problem**, który próbuje rozwiązać pull request. Może być osadzony w większym kontekście w GitHubowej dyskusji lub problemie.

* Jest też duża szansa, że pull request nie jest konieczny, ponieważ problem można rozwiązać w **inny sposób**. Wtedy możesz to zasugerować lub o to zapytać.
