apache proxy config

Good day,

I'd like my ISPConfig server to help deliver Golang web sites.

I figure all I have to do is create an environment, put the executable binary in the web folder and run the Go app server as a service on say port 8888 (no problem for me here).

Which Apache file should I modify for port 80 and 443 to redirect to 8888 ?
- I see /etc/apache2/sites-available/a_site.ca.vhost, can I modify this or this is generated from something else?
- Could it be done though Sites / Options / Apache directives ?
- Is there a classic snipet I can put somewhere? Someone must have redirected a port in ISPConfig in the past?

I figure I could benefit from everything that ISPConfig provides, for example, Let's Encrypt, db, email, DKIM, backups, stats like every other site.

Thanks ahead,

JP

 

OK, I'll experiment with this. Thanks for the tip.
(probably better with an Nginx setup for this eventually)
