Can Splunk be served from a different endpoint?

[sh4kesbeer]

I am currently trying to let splunk run behind a reverse proxy so that there can be multiple web-services on the same domain.
The goal is to run splunk from e.g.:

https://example.com:9000/abc/

so that this maps to e.g.

http://some-local-machine:8000/ 

where splunk is running at port 8000.
I was able to configure nginx to handle normal requests and even the redirects coming form splunkweb in the right way but it seems some of the assets contained in the page are not referenced relative to the current page but rather contain an absolute path which is determined based on the Host-field in the request issued from the proxy.
Is there some way to let splunk know that it is supposed to run from some other endpoint than /? So that it can inject this endpoint into all links (by prefixing them) that are needed for the dynamic parts of the page.
Thanks in advance!

Okay there is a root_endpoint option for the web.conf which works as expected. It seems I did oversee this initially
