推荐答案

我一直在寻找一个类似的答案停止FF等浏览器抛出我的服务器端页面数。

I was looking for a similar answer to stop FF and other browsers throwing out my server side page counts.

• 火狐


• 铬白皮书

• Firefox
• Chrome white paper

根据上述文章，火狐发送一个报头，这使得它易于检测，但铬白皮书指出Chrome不给出任何指示给服务器。在Chrome白皮书指出，当他们使用的<一个外部的分析解决方案（用JS脚本）则不会计入prefetch命中href=\"https://developer.mozilla.org/en-US/docs/Web/Guide/User_experience/Using_the_Page_Visibility_API\"相对=nofollow>页知名度API 。

According to the articles above, Firefox sends a header which makes it easy to detect but the Chrome white paper states that Chrome doesn't give any indication to the server. The Chrome white paper notes that external analytic solutions (scripts written in JS) will not count the prefetch hits when they use the page visibility API.

我的建议是写自己的JS脚本，如果页面是不断可见检测。

My suggestion is to write your own JS script to detect if the page is ever made visible.
