在Apache Proxy后面运行多个Node.js服务器

Question

I'm running multiple Node.js Server on different ports and using Websocket in my client to connect with these different servers. Clients are making Ajax calls without websocket also using given server ports and everything is working fine.

Now the problem is that because I'm using nonstandard ports to run multiple node.js server so while making calls from client side, they are being blocked by firewall. So I want to introduce an Apache proxy in between and send all the retests to apache on standard port 80 and then interact with multiple Node.js servers in the background. I tried to explain existing and desired senario in attached file.

Need your help to have appropriate Apache proxy configuration to make it work.

You can probably try with virtual host and proxy pass eg

    <VirtualHost *:80>
        ProxyRequests off
        <Proxy *>
                Order deny,allow
                #Require all granted
                Allow from all
        </Proxy>

        ProxyPass /A?query http://example.com/app
        ProxyPassReverse /A?query http://example.com/app

        ProxyPass /B?query http://localhost:8081/$1
        ProxyPassReverse/B?query http://localhost:8081/$1

        ProxyPassMatch "^(/.{1,})$" http://localhost:8082/$1
        ProxyPassReverse "^(/.{1,})$" http://localhost:8082/$1

  </VirtualHost>
