Server

Server 標頭描述處理請求的伺服器軟體資訊：也就是產生回應的伺服器資訊。

警告： 請避免 Server 值的資訊過度冗長與詳盡，因為它們可能會洩漏實做細節、讓攻擊者容易找到已知安全漏洞並利用之。

標頭類型 Response header (en-US)
Forbidden header name (en-US) 否

語法

Server: <product>

指令

<product>

處理請求的軟體（或組件）名。語法通常與 User-Agent 相似。

How much detail to include is an interesting balance to strike; exposing the OS version is probably a bad idea, as mentioned in the earlier warning about overly-detailed values. However, exposed Apache versions helped browsers work around a bug those versions had with Content-Encoding (en-US) combined with Range (en-US).

示例

Server: Apache/2.4.1 (Unix)
