 !!! bug
     Currently, the `BaseHTTPMiddleware` has some known issues:
 
-    - It's not possible to use multiple `BaseHTTPMiddleware` based middlewares.
-    - It's not possible to use `BackgroundTasks` with `BaseHTTPMiddleware`.
-    - Using `BaseHTTPMiddleware` will prevent changes to `contextlib.ContextVar`s from propagating upwards. That is, if you set a value for a `ContextVar` in your endpoint and try to read it from a middleware you will find that the value is not the same value you set in your endpoint (see [this test](https://github.com/encode/starlette/blob/621abc747a6604825190b93467918a0ec6456a24/tests/middleware/test_base.py#L192-L223) for an example of this behavior).
