Describe the bug
As stated in https://community.containo.us/t/traefik-routing-issues/624/4, when GLPI is behind a context, content is not served in the correct way which causes to load invalid links.

A clear and concise description of what the bug is.
The HTML generated by GLPI starts with /xxxx,
(example <script type="text/javascript" src="/lib/jquery/js/jquery.min.js?v=9.4.3"></script>),
which are assuming the webapp is always served under the root path of the website (aka. /).
GLPI is not built for supporting hosting behind a context by default.

Hi,

I often use GLPI hosting behind a context (i.e. http://my.domain/glpi/) and I did not face this issue. However, I never used GLPI behind a context AND a proxy, so I cannot says if it is a server configuration issue or a case that is not handled correctly by the application.

The "context" is computed by the method Config::detectRootDoc(). It may help you to debug. If you find a solution, feel free to open a pull request.
