带有大量 POST 上传和我的 apache 的坏网关 +清漆 +克隆设置
这是一个相当复杂的场景，因此我非常感谢任何指向正确方向的指针。
所以我在服务器 A 上设置了 apache 来代理服务器 B 的 https 流量，这是一个 varnish 和 apache 背后的克隆站点。
我连接到 A 并且可以在 https 上浏览该网站，一切都很好。然而，当我通过 plone 的 POST 表单上传文件时，问题就开始了。我可以上传小文件（~1 MB），但是当我尝试上传 50MB 文件时，我一直等待文件上传，当指示为 100% 时，我得到一个错误的网关（代理服务器收到来自上游服务器的无效响应。）
在我看来，A 和 B 的通信之间出现了超时，并且没有被重定向到正确的 url，而是收到了错误的网关，更不用说文件未上传。
在 apache 日志上，我看到
[error] proxy: pass request body failed
正如其他线程上的建议，我尝试了以下值，但没有运气
force-proxy-request-1.0
proxy-nokeepalive
KeepAlive
KeepAliveTimeout
proxy-initial-not-pooled
Timeout
ProxyTimeout
Sooooo..有什么建议吗？提前一百万致谢！
This is a rather complicated scenario, so I would highly appreciate any pointer to the correct direction.
So I have setup apache on server A to proxy https traffic το server B, that is a plone site behind varnish and apache.
I connect to A and can browse the site on https, everything is fine. However, problems start when I upload files, via plone's POST forms. I can upload small files (~1 MB), but when I try to upload a 50MB file, I wait all the time till the file is uploaded, and when the indication is 100%, I get a Bad gateway (The proxy server received an invalid response from an upstream server.)
It seems to me that something timeouts between the communication of A and B and instead of being redirected to the correct url, I get a Bad gateway, not to mention that the file is not uploaded.
On the apache log I see
[error] proxy: pass request body failed
As suggested on other threads, I've experimented with the following values with no luck
force-proxy-request-1.0
proxy-nokeepalive
KeepAlive
KeepAliveTimeout
proxy-initial-not-pooled
Timeout
ProxyTimeout
Sooooo..any suggestions? Thanks a million in advance!

你检查过清漆配置吗？ varnish 有自己的一些超时，我熟悉 send_timeout ，如果在几秒钟内无法完成，它通常会中断下载（varnish 对于大型下载确实没有任何好处，因为你最终会做一些愚蠢的事情，例如配置 send_timeout=7200 来使其发挥作用）。
另外，为该后端将first_byte_timeout设置为更大的数字，因为大文件上传可能会延迟plone的响应，足以导致这种情况。
Did you check the varnish configuration? varnish has some timeouts of its own, I am familiar with send_timeout which usually breaks downloads if they fail to finish within a few seconds (Varnish really isn't any good for large downloads, because you end doing stupid things like configuring send_timeout=7200 to make it work).
Also, set first_byte_timeout to a larger number for that backend, because a large file upload might delay plone's response just enough to cause this.
在 apache 虚拟主机文件中设置 Timeout 和 KeepAliveTimeout 对我有用。
例子：
Setting the
