REASON 为一指示请求者询问的实体被移除的原因的数值编码。其编码如下：
0 其它的原因
1 原服务器告诉我此实体并不存在
RESPONSE 编码如下：
0 我曾经有过，现在没有了
1 我有，且一直保留着，为提供原因
2 我没有
CLR 响应没有OP-DATA 。
没有具体指明响应、实体、或者存储区标题就清除一URI意味着清除所有的使用此URI的实体。RD 为真。
7. 安全考虑
If the optional AUTH element is not used, it is possible for unauthorized third parties to both view and modify a cache using the HTCP protocol.
8. 感谢
Mattias Wingstedt of Idonex brought key insights to the development
of this protocol. David Hankins helped clarify this document.
