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

If a conditional GET was successful, responses from the network and cache are merged as directed by the spec.

## Follow-up Requests

When your requested URL has moved, the webserver will return a response code like `302` to indicate the document’s new URL. OkHttp will follow the redirect to retrieve a final response.

        final ExecResult execResult = execOperations.exec(spec -> {
            // The redundant cast is to silence a compiler warning.
            spec.setCommandLine((Object[]) args);
            spec.setStandardOutput(stdout);
            spec.setErrorOutput(stderr);
            spec.setIgnoreExitValue(true);
        });
