我已经在 launchpad.net 和 BugZilla 上提交了错误报告，但我想确认是否有人遇到过此问题。我们使用 apache2 作为客户网站的反向代理服务器。有时，虽然是随机的，但在所有请求的 2% 中，我们得到的不是正常的响应内容，而是一种双重响应：响应 A，然后是响应 B 的标头，然后是响应 B。这非常烦人，因为网站对客户非常重要，而一个无法正常运行的网站可能会吓跑用户。
如果我们直接访问 Web 服务器，即不使用代理服务器，则完全没有问题。
我可以在这里重复整个故事（并且当被要求时我会这样做），但我希望错误报告的链接就足够了：https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1874932
当我以为这是 Web 服务器上的编程问题时，StackOverflow 上的原始问题如下：https://stackoverflow.com/questions/61304769/xpages-server-sends-wrong-data-apache2-problem
再次，我的问题是：有人熟悉这种现象吗？如果是的话，有快速解决方法吗？或者我们应该选择不同的反向代理服务器？
感谢您的帮助！

答案1
很遗憾，这个问题现在已经“解决”了，因为我们准备切换到 nginx……我们遇到了一些问题，但不是上面讨论的溢出问题。当然，这个错误仍然存在于 Apache 中。
