Is it possible to set a custom webroot for reverse proxying on different url base path ?

[Dark4Codrutz]

as the title suggests, I was trying to figure out if OITC exposes some variable that overwrites app's requests base url.

What I need to achieve is to have OITC webapp GET requests get redirected to the correct URL path when running behind a reverse proxy with a prefix.

For example:
I am reverse proxying OITC from www.website.com/monitor.
As soon as the webapp loads it queries for www.website.com/users/login instead of www.website.com/monitor/users/login.

In the past I've been able to solve these kind of cases, where webapp uses absolute paths instead of relative paths, by configuring the webapp to use a different base url path, changing the default / to /monitor as per my example.

For php I've seen nextcloud doing it like this
https://docs.nextcloud.com/server/stable/admin_manual/configuration_server/reverse_proxy_configuration.html#overwrite-parameters

Is there anything similar available in OITC ?

Hi @Dark4Codrutz

Currently wo do not have such an configuration option.

I would recommend to go with an subdomain like monitor.website.com. This does not require any hacks for configuration changes

If you really like to tinker around, we do something similar with our internal Grafana. (sub_filter).

openITCOCKPIT/system/etc/nginx/openitc/master.conf

Lines 93 to 105 in e83c22e

	#Proxy for Grafana (external requests done by Web browsers)
	# Not used by API Requests of openITCOCKPIT
	location ^~ /grafana/ {
	# Send request to authentication code first
	auth_request /auth_grafana;
	auth_request_set $auth_status $upstream_status;
	proxy_set_header X-WEBAUTH-USER viewer;
	proxy_set_header Authorization "";
	proxy_pass http://127.0.0.1:3033/;
	sub_filter 'http://localhost:3033/grafana/' 'https://$host/grafana/';
	sub_filter_once off;
