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。
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。

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 combined with Range.
示例
Server: Apache/2.4.1 (Unix)
