服务端 用的 python的flask框架
返回静态文件代码如下
flask.send_file('../static/js/main.js',cache_timeout=0)
request headers如下:
<code>GET /static/js/main.js?__inline=true HTTP/1.1 Host: anglestreet.duapp.com Connection: keep-alive Cache-Control: max-age=0 Accept: */* If-None-Match: "flask-1409227359.0-21401-527044139" If-Modified-Since: Thu, 28 Aug 2014 12:02:39 GMT User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/36.0.1985.125 Chrome/36.0.1985.125 Safari/537.36 DNT: 1 Referer: http://anglestreet.duapp.com/ Accept-Encoding: gzip,deflate,sdch Accept-Language: zh,zh-CN;q=0.8 Cookie: BAEID=81F2D83EAD7D00091521BA62EDC1894B:FG=1; </code>

在chrome浏览器下无问题. 在微信链接中打开则经常出现版本过期的情况, 必须手动刷新

问题在于Cache-Control: public, max-age=0,设为Cache-Control: private就不会缓存页面
我也遇到了同样的问题,场景如下:
在a页面只能显示点赞的数量,点击点赞图标可以进入b页面,在b页面可以点赞或者取消点赞。
现在在a页面点赞数为0,我进入b页面点赞,点赞成功以后按安卓手机的返回键回到a页面,但是a页面的点赞数并没有加1。。。 试用了很多方法也不行,楼主的问题解决了吗
