If an incoming request does not validate correctly then a `400` response will be sent.

## `GZipMiddleware` { #gzipmiddleware }

Handles GZip responses for any request that includes `"gzip"` in the `Accept-Encoding` header.

The middleware will handle both standard and streaming responses.

The following arguments are supported:

                    // Handle nested properties
                    if (key.contains(".")) {
                        // Simple nested property handling for testing
                        result = result.replace("${" + key + "}", String.valueOf(value));
                    } else if (value instanceof TestUser) {
                        // Handle TestUser object

Some of the options you could use as a TLS Termination Proxy are:

* Traefik (that can also handle certificate renewals)
* Caddy (that can also handle certificate renewals)
* Nginx
* HAProxy

## Let's Encrypt { #lets-encrypt }

Before Let's Encrypt, these **HTTPS certificates** were sold by trusted third parties.

In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.
