thoroughly before moving to code.

Some examples of types of pull requests that are immediately helpful:

  - Fixing a bug without changing a public API.
  - Fixing or improving documentation.
  - Improvements to Maven configuration.

Guidelines for any code contributions:

1.  Any significant changes should be accompanied by tests. The project already
    has good test coverage, so look at some existing tests if you're unsure how

 * {{{./apidocs/org/apache/maven/plugin/PluginParameterExpressionEvaluator.html}PluginParameterExpressionEvaluator}}, used to
 evaluate plugin parameters values during Mojo configuration,

 * <<<ExceptionHandler>>> component ({{{./apidocs/org/apache/maven/exception/ExceptionHandler.html}javadoc}}),
 with its <<<DefaultExceptionHandler>>> implementation

```

Testing with an example

Garante que todas as requisições recebidas tenham um cabeçalho `Host` corretamente configurado, a fim de proteger contra ataques de cabeçalho de host HTTP.

En la sección sobre **deployment** verás cómo configurar HTTPS de forma gratuita, usando Traefik y Let's Encrypt.
