Proxy Websockets and HTTP through the same location in Nginx?

Proxy Websockets and HTTP through the same location in Nginx?

Yes, you can proxy both WebSockets and HTTP traffic through the same location in Nginx. Nginx has built-in support for handling both WebSocket and HTTP requests.

To configure Nginx to proxy WebSockets and HTTP traffic through the same location, you can use the proxy_pass directive along with appropriate settings.

Here’s an example configuration:

server {
listen 80;
server_name example.com;
location /myapp {
proxy_pass http://backend-server;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection “upgrade”;
}
}

In the above configuration:

  • The location /myapp directive specifies the location where the requests will be proxied.
  • proxy_pass specifies the backend server to which the requests will be forwarded. Replace http://backend-server with the appropriate URL or IP address of your backend server.
  • proxy_http_version 1.1 sets the HTTP version to 1.1, which is required for WebSocket connections.
  • proxy_set_header Upgrade $http_upgrade and proxy_set_header Connection "upgrade" are necessary headers for WebSocket connections. They allow Nginx to handle WebSocket upgrade requests correctly.

With this configuration, Nginx will proxy both WebSocket and HTTP requests for the specified location (/myapp in this example) to the backend server.

You can adapt this configuration to match your specific requirements, such as using SSL/TLS, specifying additional proxy settings, or configuring multiple locations for different services.

Make sure to test and validate the configuration to ensure that WebSocket and HTTP traffic is being properly proxied through Nginx.
