HEAD 请求

Returns the same HTTP response headers as a GET request, but without the response body. This allows retrieving meta-information from the response headers without transporting the entire content. The meta-information includes the media type,字符编码，压缩编码，实体内容长度等。

A HEAD request can be used to check if forestBasedClassificationFit 资源是否存在，或者客户端是否有权限访问 forestBasedClassificationFit 资源。通过对加.<format>的 URI 执行 HEAD 请求，还可以快速判断 forestBasedClassificationFit 资源是否支持<format>格式的表述。
