Question

我在两台IIS服务器前安装了Nginx。主要目标是加载平衡，ssl卸载和缓存静态内容。

当所有上游服务器不可用或丢失404错误时，我正面临着一个非常艰难的时刻。我在我的NginX盒子上创建了一个maintenance.html文件，但无法加载它。我有时可以加载IIS 404s，有时可以加载默认的NginX 404.我真正想要做的是，如果由于某种原因所有上游都关闭或投掷404s是为了向用户显示“维护”页面并最终在该页面中放入一些代码以提醒我所有上游服务器都已关闭。

这是我的配置：

# Backend IIS Servers
upstream backend-iis {

    # Health Checks
    #healthcheck_enabled;

你正在使用免费版吗？

我认为您所寻找的是名为NGINX Plus的非免费版本。

使用NginX作为反向代理时，如何回退到维护URL？
