Proxy support with a subpath

[GaPhi]

What would you like to be added:
Support of a subpath URL to access TeslaMate, like in Grafana for example.
- GF_SERVER_DOMAIN=www.myorg.com
- GF_SERVER_ROOT_URL=%(protocol)s://%(domain)s:%(http_port)s/grafana/
- GF_SERVER_SERVE_FROM_SUB_PATH=true
And in Apache2 :
ProxyPass "/grafana" "http://localip:3000/grafana"
ProxyPassReverse "/grafana" "http://localip:3000/grafana"

Why is this needed:
I would like to use a single public hostname but access several services with a subpath :

• /grafana
• /teslamate
• ...

Additional context:
Already working with Grafana and other services but did not succeed with TeslaMate (no dedicated setting found, and Apache2 config file is not sufficient).
ProxyPass "/teslamate" "http://localip:4000/"
ProxyPassReverse "/teslamate" "http://localip:4000/"

Hi @GaPhi looks like @tacotran had posted what you need, while trying to help me. See HERE.

Does that help?

Hi, thank you for the link.

I think it is just part of the solution as the teslamate URI shall still be a root base (/index.html is teslamate, I would like to have /teslamate/index.html to be the base of all the URI).

Or did I miss something ?

Welcome @GaPhi. I recommend reaching out to @tacotran (tagged here) in case he may be able to help you tweak his solution... If you do get it to work, kindly share a detailed tutorial, so others can benefit as well.
