如何识别服务器场中的哪个 Web 服务器处理了请求? [英] How to identify which web server in a farm served a request?

问题描述

我们正在调试在 IIS7 上运行的网站的间歇性问题.

We're debugging intermittent issues with a website running on IIS7.

由于负载均衡器后面有许多节点，我们无法判断哪个主机响应了给定请求.在 IIS 级别有什么方法可以指定哪个主机服务于请求?例如，IIS 是否可以在响应中附加一个标头来指示发送响应的主机的 IP?

Since we have many nodes behind the load balancer, we can't tell which host responded to a given request. Is there any way at the IIS level to specify which host served a request? For example, could IIS append a header in the response that indicates the IP of the host that sent the response?

理想情况下，我想要一个不需要任何编码的解决方案.

Ideally, I would like a solution that does not require any coding.

推荐答案

无需编写任何代码，您只需在 IIS 管理器中为每台计算机配置自定义 HTTP 响应标头即可.您需要使用 GUI 或 APPCMD.EXE 手动输入每个 IP 地址或标识符.这可以在全球范围内为所有站点完成:

Without writing any code you could just configure a custom HTTP Response Header for each machine in IIS Manager. You'd need to manually enter each IP address or identifier manually using either the GUI or APPCMD.EXE. This can be done globally for all sites:

appcmd.exe set config -section:system.webServer/httpProtocol 
              /+"customHeaders.[name='X-Custom-Name',value='MyCustomValue']"

或者对于单个站点:

appcmd.exe set config "Default Web Site" -section:system.webServer/httpProtocol 
              /+"customHeaders.[name='X-Custom-Name',value='MyCustomValue']"

为了适应它们，我将这些命令分成两行.您应该将它们作为一行输入.

I've split these commands over two lines just to fit them in. You should enter them as a single line.
