451 Unavailable For Legal Reasons

HTTP 451 Unavailable For Legal Reasons客户端错误响应代码指示用户请求由于法律原因而不可用的资源，例如已发出法律行为的网页。

状态

451 Unavailable For Legal Reasons

示例

此示例响应取自 IETF RFC（请参阅下文），并包含对 Monty Python 的 Brian 生活的引用。

请注意，Link标题还可能包含一个rel="blocked-by"关系，用于标识实际实施封锁的实体，而不是任何其他实体实施封锁的实体。

任何试图识别最终对资源不可用的实体负责的企图，如提出合法请求而导致内容被移除的个人或组织的名称都属于响应主体，而不在rel="blocked-by"链接中。
