TL; DR：通过Apache ReverseProxy将超过5分钟的Web任务出错。 时间较短的任务/报告成功。 直接访问报告成功（ http：//internalserver/foobar.aspx而不是http://public.mycompany.com/foobar.aspx ）。 我应该在哪里看，我缺less什么超时？
我有一个Apache实例切换到HTTPS，然后ProxyPassing一个请求沿着它的快乐方式…到Windows Server 2012 R2 IIS 8实例。
Browser <==> Apache 2.2.15 <==> IIS 8 (Windows 2012 R2, IIS 8.5.9600.16384) <==> Web App (<==> database) 一切都只是厚脸皮 – 直到一个“长时间运行”的报告被启动。 直接在Windows服务器上运行时，报告需要大约6分钟。 当从浏览器运行时，更短的报告成功 – 但这最终失败。
网页错误：

我们已经尝试将所有超时设置增加到1200（20分钟） – 在Apache和IIS中。
我错过了什么？ 什么可能导致Apache和IIS之间的proxyerror消息？
