Proxy_pass 相当于 HAProxy

Question

什么是 Nginx pass_proxy HAProxy 中的这个

location /{
    proxy_pass https://WebApplication.azurewebsites.net;
  }

我尝试测试此配置，但当我指向具有以下配置的任何后端服务器时收到 404，但未在根目录上使用 ACL，例如使用自签名证书

指向任何使用 bing、google 作为 url 测试的后端服务器时，我收到 404 ...

Answer 1

我建议使用以下配置

frontend fe_http_sne_in
bind *:443 ssl crt /etc/ssl/private/mydomain.pem
option forwardfor
use_backend be_sne_insecure if { path_beg /test}
default_backend be_default

backend be_default
...

backend be_sne_insecure
mode http 
option forwardfor
http-request replace-header Host .* WebApplication.azurewebsites.net 
server srv01 WebApplication.azurewebsites.net:443 ssl verify none
