java - 刷新页面间隔出现412

Question

登录进首页后，刷新页面，第一次报412错误，第二次刷新正常，第三次继续412，如是，度娘后说是可能是ajax post请求导致head 头文件关于缓存不符，去掉post方法后还是报错，请问哪位有经验的指教下，先行谢过

Answer 1

Could you please tell me if the poster has solved this problem? I am also encountering this problem and I don’t know the reason. I tried Baidu but couldn’t find a suitable solution

Answer 2

I also encountered the 412 error recently. Appears when loading videos under Chrome. ETag question
