在默認的情況ASP.NET框架，會出現如下

[[email protected] ~]# curl -I http://127.0.0.1
HTTP/1.1 200 OK
Server: VWS/1.0
Date: Sun, 10 Sep 2017 00:58:56 GMT
Content-Length: 0
Connection: keep-alive
Cache-Control: private
Set-Cookie: ASP.NET_SessionId=djoozwy53q55gjol5cizjsoo; path=/; HttpOnly

這樣一下就知道是采用.NET開發，現在我們就通過修改web.config文件修改頭部名稱

 <system.web>
    <sessionState cookieName="SessID" />
</system.web>

這樣就可以

[[email protected] ~]# curl -I http://127.0.0.1
HTTP/1.1 200 OK
Server: VWS/1.0
Date: Sun, 10 Sep 2017 01:19:55 GMT
Content-Length: 0
Connection: keep-alive
Cache-Control: private
Set-Cookie: SessID=eznygdvlh1ewwuk4wfdg5ogk; path=/; HttpOnly
