If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

In these cases, it could make sense to store the tags in an `Enum`.

**FastAPI** supports that the same way as with plain strings:

{* ../../docs_src/path_operation_configuration/tutorial002b_py310.py hl[1,8:10,13,18] *}

    Map<Element, Element> map = mapToTest;

    boolean dummy = false;
    for (int i = 0; i < reps; i++) {
      for (Element key : map.values()) {
        // This normally wouldn't make sense, but because our keys are our values it kind of does
        Element value = map.get(key);
        dummy ^= key != value;
      }
    }
    return dummy;
  }

They work the same way as for other FastAPI endpoints/*path operations*:

{* ../../docs_src/websockets_/tutorial002_an_py310.py hl[68:69,82] *}

As this is a WebSocket it doesn't really make sense to raise an `HTTPException`, instead we raise a `WebSocketException`.

You can use a closing code from the [valid codes defined in the specification](https://tools.ietf.org/html/rfc6455#section-7.4.1).

### Burger Conclusion { #burger-conclusion }

In this scenario of "fast food burgers with your crush", as there is a lot of waiting 🕙, it makes a lot more sense to have a concurrent system ⏸🔀⏯.

This is the case for most of the web applications.

Many, many users, but your server is waiting 🕙 for their not-so-good connection to send their requests.
