設置response頭信息禁止緩存

java代碼中可通過如下代碼設置

response.setHeader("Pragma", "No-Cache");
response.setHeader("Cache-Control", "No-Cache");
response.setDateHeader("Expires", 0);

同理，nginx服務器上也可通過給nginx添加響應頭，讓html,css,js不緩存

nginx.conf

location / {

add_header Cache-Control no-cache;

add_header Pragma no-cache;

add_header Expires 0;

}
