# HTTPConnection class¶

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.

You can import it from `fastapi.requests`:

```
from fastapi.requests import HTTPConnection
```

## fastapi.requests.HTTPConnection [¶](#fastapirequestshttpconnection-)

```
HTTPConnection(scope, receive=None)
```

Bases: `Mapping[str, Any]`, `Generic[StateT]`

A base class for incoming HTTP connections, that is used to provide any functionality that is common to both `Request` and `WebSocket`.

    assert scope["type"] in ("http", "websocket")
