### `HTMLResponse` { #htmlresponse }

Toma algún texto o bytes y devuelve un response HTML, como leíste arriba.

### `PlainTextResponse` { #plaintextresponse }

Toma algún texto o bytes y devuelve un response de texto plano.

### Override the `HTTPException` error handler { #override-the-httpexception-error-handler }

The same way, you can override the `HTTPException` handler.

For example, you could want to return a plain text response instead of JSON for these errors:

{* ../../docs_src/handling_errors/tutorial004_py310.py hl[3:4,9:11,25] *}

/// note | Technical Details

But if we use the same model for another *path operation*, we could be sending our user's passwords to every client.

/// danger

Never store the plain password of a user or send it in a response like this, unless you know all the caveats and you know what you are doing.

### Deploy a more secure control plane with kubeadm

A new alpha feature allows running the kubeadm control plane components as non-root users. This is a long requested security measure in kubeadm. To try it you must enable the kubeadm-specific `RootlessControlPlane` feature gate. When you deploy a cluster using this alpha feature, your control plane runs with lower privileges.
