Вы можете настроить `Form` точно так же, как настраиваете и  `Body` ( `Query`, `Path`, `Cookie`), включая валидации, примеры, псевдонимы (например, `user-name` вместо `username`) и т.д.

/// info | "Дополнительная информация"

`Form` - это класс, который наследуется непосредственно от `Body`.

### Rewriting Requests

Interceptors can add, remove, or replace request headers. They can also transform the body of those requests that have one. For example, you can use an application interceptor to add request body compression if you're connecting to a webserver known to support it.

```java
/** This interceptor compresses the HTTP request body. Many webservers can't handle this! */
final class GzipRequestInterceptor implements Interceptor {

	// Corrupted XML
	malformedReq := &http.Request{
		Body:          io.NopCloser(bytes.NewReader([]byte("<>"))),
		ContentLength: int64(len("<>")),
	}

	// Not an XML
	badRequest := &http.Request{
		Body:          io.NopCloser(bytes.NewReader([]byte("garbage"))),
		ContentLength: int64(len("garbage")),
	}

	// generates the input request with XML bucket configuration set to the request body.
