Nginx forward proxy domain configuration

What is Nginx forward proxy?

In network communication, forward proxy is a mode of use for proxy servers. When a client sends a request to a proxy server, the request is forwarded through the proxy server to the target server, which then forwards the response from the target server to the client.Nginx, as a high-performance web server and reverse proxy server, can also be configured to act as a forward proxy server to enable access to external resources.Configuration of the Nginx forward proxy requires some adjustments to the Nginx forward proxy configuration requires some tweaking of Nginx settings to accommodate forwarding access to a specific target server.

Configuration steps for Nginx forward proxy domains

1. First, define a new upstream in the Nginx configuration file that specifies the address and port of the target server to be proxied, for example:

upstream target_server {
server 192.168.1.100:80;
}

2. Then, configure the forward proxy's location block in Nginx's configuration file and use the proxy_pass directive to forward the request to the target server, for example:

server {
listen 80; server_name proxy_server; server_name
server_name proxy_server;

location / {
proxy_pass http://target_server;
}
}

How do I verify that the Nginx forward proxy is configured successfully?

To verify that the Nginx forward proxy is configured successfully, you can check the Nginx access logs and the target server access logs after the client initiates a request to verify that the request was successfully forwarded to the target server. In addition, you can also verify that the configuration has taken effect by setting up a proxy server on the client side to make a network request, and then checking whether the target server has received the corresponding request.
