[PieterL75]

Suzieq version

0.21.0

Install Type

hand deployed python

Python version

3.9

Impacted component

suzieq-gui

Steps to Reproduce

deploy suzieq-gui on a relative path

• gui listener : 127.0.0.1:8051
• nginx redirects https://server/suzieq to 127.0.0.1:8051 Open the trace page start a trace click on one of the image/arrows

Expected Behavior

the link opens with a relative url to the fqdn. https://hostname/suzieq/?variables

Observed Behavior

the link is rewritten to https://hostname/?variables

Screenshots

Additional Context

This is done in the get_base_url(): https://github.com/netenglabs/suzieq/blob/develop/suzieq/gui/stlit/guiutils.py#L112

The logic there is not quite ok, it should just return "?variable=value", and let the browser handle the relative path
