A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

In general, ASGI middlewares are classes that expect to receive an ASGI app as the first argument.

So, in the documentation for third-party ASGI middlewares they will probably tell you to do something like:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

import jcifs.internal.smb2.Smb2Constants;
import jcifs.internal.util.SMBUtil;

/**
 * SMB2 Change Notify request message.
 *
 * This command is used to monitor a directory for changes
 * and receive notifications when modifications occur.
 *
 * @author mbechler
 */
public class Smb2ChangeNotifyRequest extends ServerMessageBlock2Request<Smb2ChangeNotifyResponse> {

    /**

To create a middleware you use the decorator `@app.middleware("http")` on top of a function.

The middleware function receives:

* The `request`.
* A function `call_next` that will receive the `request` as a parameter.
    * This function will pass the `request` to the corresponding *path operation*.
    * Then it returns the `response` generated by the corresponding *path operation*.
