打開 nginx 配置文件: vim nginx.conf,編輯:
http {
include mime.types;
default_type application/octet-stream;
add_header Cache-Control max-age=300; //添加這樣的代碼
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
保存后退出!然后驗證
[root@nginx sbin]# ./nginx -t //檢查配置文件, -t : test configuration and exit
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
測試驗證,成功!
[root@nginx sbin]# curl -I "http://192.168.202.130/icon.png"
HTTP/1.1 200 OK
Server: nginx/1.10.1

ETag: "5788a664-1fc5"
Cache-Control: max-age=300 // nginx設置的header: cache-control 生效!
Accept-Ranges: bytes
然后驗證緩存服務器ATS的Cache-Control信息:
[root@nginx ~]# curl -I "HTTP://192.268.202.129/icon.png"
HTTP/1.1 200 OK
Server: nginx
Date: Mon, 25 Jul 2016 04:35:08 GMT
Content-Type: text/html
Content-Length: 164
Last-Modified: Wed, 25 Mar 2015 09:33:00 GMT
Connection: close
Accept-Ranges: bytes
通過ATS服務器進行從NGINX下載測試文件發現並沒有Cache-Control頭信息
[root@nginx ~]# curl -I "http://192.168.202.129/icon.png"
HTTP/1.1 200 OK
