Multiple Proxy/ReverseProxy on Apache

Question

I have a service on port 3000 with Proxy/ReverseProxy on Apache at Port 80 on http://myserver/foo.

I want to put another server on port 3456 and Proxy/ReverseProxy it from http://myserver/bar on Apache as well.

What would be the best strategy?

My foo.conf on httpd/conf.d

<VirtualHost *:80>
  RewriteEngine on
  RewriteRule ^/?$ /foo/ [R=permanent,L]
  <Location "/foo">
    ProxyPass http://localhost:3000
  </Location>
  ProxyPassReverse /foo http://localhost:3000 
  ProxyPreserveHost On
</VirtualHost>

You can basically just repeat what you already have for the /bar URL-path as well. Except you'll need to move the existing ProxyPassReverse directive inside the <Location> section. (In your current config, you don't strictly need the <Location> section.)

For example:

<VirtualHost *:80>
  RewriteEngine on
  RewriteRule ^/?$ /foo/ [R=permanent,L]

  ProxyPreserveHost On
  <Location "/foo">
    ProxyPass http://localhost:3000
    ProxyPassReverse http://localhost:3000 
  </Location>
  <Location "/bar">
    ProxyPass http://localhost:3456
    ProxyPassReverse http://localhost:3456
  </Location>
</VirtualHost>

Although this <VirtualHost> container would seem incomplete since you have no ServerName (ServerAlias, ErrorLog, etc.) directive(s). So I assume these are already defined in the main server config?
