当我加载一个 html 页面时，我有 5 个字符串，间隔大约一秒。
<br>1</br>
...... 1 second ......
<br>2</br>
...... 1 second ......
<br>3</br>
...... 1 second ......
<br>4</br>
...... 1 second ......
<br>5</br>
...... 1 second ......
--- end request ---
Chromium 和 Firefox 都加载并显示第一个 br，然后显示接收到的下一个。 (但是 Firefox 需要内容编码)。但是在请求结束之前，Safari 拒绝显示任何标签。
Chromium 似乎可以做到这一点。
Firefox首先需要判断内容编码https://bugzilla.mozilla.org/show_bug.cgi?id=647203
但 Safari 似乎只是拒绝。是否需要不同的响应代码或 header ？我尝试将内容类型明确设置为 text/html。没用。
我已经在 Wireshark 中确认字符串是分开发送的，即它们没有被缓存并一次发送。
我还确认，如果我通过本地主机或使用我的公共(public) IP 地址，就会发生这种情况。
我试过content-length和keep alive，前者只是自动关闭请求，后者似乎没有效果。

最佳答案
您是在 Windows 版 Safari 上尝试这个吗？如果是，那么它不再正式支持。如果您尝试在 Safari for Mac 上解决此问题，请创建演示或共享链接(如果您已有)。
我可以测试并帮助你解决这个问题。
