ios - Mobile Safari iOS 9.3 发出多个 HTTP 请求，最终显示错误

Question

在 iOS 9.3 更新后，以前可以使用的网站不再可用。我们在移动版 Safari 中收到以下错误:

A problem occurred with this webpage so it was reloaded

和

A problem repeatedly occured on "http://domain.ch/en/search/rent/f/"

起初我们以为正在进行无休止的重定向。但事实并非如此。

• 该网站适用于所有其他浏览器，适用于 iOS 9.2(未对代码进行任何更改)
• iOS Safari 发送多个请求，即使第一个请求已成功返回(HTTP 状态 200)

这是访问日志:

我目前不知道这可能是什么原因。

我发布这篇文章是希望其他人在 iOS 9.3 更新后遇到过类似的事情，并对这种奇怪的行为有一些了解。

Answer 1

经过一些调试，我们发现如果我们删除 CSS，它就可以工作。

问题是网络字体。更具体地说，它是网络字体的 WOFF 变体。它导致 Safari 崩溃。我们交换后，一切恢复正常。

我想在 iOS 9.2 Safari 中使用了不同的字体格式(可能是 truetype)并且因为使用了 iOS 9.3 WOFF。这就是问题之前没有浮出水面的原因。
