- **Rule**: Pattern-based response routing (`RegexRule`, `SitemapsRule`)
- **ResponseProcessor**: `DefaultResponseProcessor`, `SitemapsResponseProcessor`, `NullResponseProcessor`
- **Transformer**: `HtmlTransformer`, `XmlTransformer`, `FileTransformer`, etc.
- **Extractor**: Weight-based selection (tries in descending weight order)
