.htaccess Mod_pagespeed不适用于make_google_analytics_async

这是我在.htaccess文件中的代码。。。而且我确信mode_pagespeed是有效的

<IfModule pagespeed_module>
ModPagespeed on
ModPagespeedEnableFilters make_google_analytics_async
.
.
.
</IfModule>

在html中，我添加了一个java脚本代码

我怎么了？这不是工作，但对于另一个过滤器插入_ga的工作，但这是没有优化

您需要用函数替换GLUE_脚本。从

其中GLUE_脚本是JavaScript，它定义了_modpagespeed_getRewriteTracker函数，以返回将同步API的所有方法映射到异步API的对象
