In the Changelog for 5.1.0 it is stated:
The support for
X-FORWARDED-*
headers has been removed because it was possible to solve it with the mandatoryurls:baseUrls
setting in an easier way.
I can’t find documentation about the use of this setting - just in singular (urls:baseUrl). Is it possible to provide a set of urls in order to login from different urls? The context is that we have a different url for each app - and it would’ve been nice if customers could use their own app url for the SquidEx login.
