没想到上线第一天就遇到了严重问题:application cache会默认缓存当前页面!!!就算咱们有如下设置:
具体代码如下:
NETWORK:*
也就是说,对于所有的动态页面,application cache会缓存起来,用户怎么刷新都是老的!
而且手机浏览器还很难清除掉,也不支持js清除!
花了一个上午,尝试了很多办法,查了很多资料,都没能清除掉客户端的缓存。一上午被用户投诉惨了。
最后还是万能的stackoverflow救了我:
Do not use appcache unless it is REALLY 100% EXACTLY WhAT YOU WANT TO DO
Even if it IS 100% EXACTLY WhAT YOU WANT TO DO, *DO NOT* use appcache until you are 100% CERTAIN that you are not going to make a single change to that page (or any file that it links to) for a LONG time.
Delete the manifest file from the server -- if the browser can't find the manifest file, then it will clear its cache... ...this will also turn caching off for everyone.
Don't turn it on again until it's 100% CORRECT
Dealing with appcache is miserable, often.
解决办法很简单,在服务器端删除掉manifest相关站点文件,并且慎用application cache
当然,也有办法是用application cache,同时能绕过自动缓存当前页面的问题。那就是用iframe
