139 哪里好了，不懂。

前段时间上海电信下欧洲的资源能跑满，剁手买了一台。最近速度能有 1m/s 就不错了，感觉掉坑里了。近日 ss 也经常超时，昨日甚至一台日本，香港，台湾都 ping 不通了，持续几小时。(手里另外一台日本香港又可以访问，走的线路不同。)

百度知道使用的办法是替换一些文字为图片，起点使用 js 输出文字。

@zhaiblog 你这视频审核了一年都没审核完...邮件催了下客服。

原来 sub_filter 不能使用正则替换，支持正则的是另外一个模块 subs_filter

@popok
不知道咋整
例如：
sub_filter '<div.*<div.*<iframe.*</iframe></div><div class="content">' '<div class="content">' r;
报错：
nginx: [emerg] invalid number of arguments in "sub_filter" directive in

如何才能正确的使用正则而不报错呢。。。

为了登录查看文章你懂的。
已实践文中提到的每个用户都生成一份缓存，效果并不明显。毕竟一般人不会不停地看同一页也就没啥命中了...目前还是没想到什么办法，打算将一用户作为公共账号进行缓存这样命中高点应该能有效果、

@fantasts 大概有点明白了，大概解决了。

就算想植入一段统计代码都不知如何是好

@popok 请问下截图那个是工具还是在线网站呢？能分享下吗？

@popok 谢谢

@popok 是我理解错了，已解决

@tmqhliu 是我理解错了，已解决

@tmqhliu 不是前面是重写后面是匹配么？

@Septembers 转换出来是没用
