Hi, Bryan. I wonder, that could be a useful feature, perhaps, what do you think, @Thomas Gasmyr.Mougang ? If we don't support this, may be it's worth to put it at Github as a feature request? Or is there a better solution that's already implemented?

I think you'd want to send this param in the redirect to the authorization request. Then you can set this variable in the context. Remember the pages are JSF, so if you read the variable from the JSF, you could then load the right resources, like css and text. So it's definitely possible, but requires a little know-how about how to write interception scripts. I'm going to close the issue because this is a little too involved for community support. What I'd suggest is to check out some of the [other Person Authn interception scripts](https://github.com/GluuFederation/oxAuth/tree/master/Server/integrations) and [pages](https://github.com/GluuFederation/oxAuth/tree/master/Server/src/main/webapp) and read the [docs](https://gluu.org/docs/gluu-server/4.2/authn-guide/intro/#authentication-interception-scripts) about scripting.

Tkanks for your response. I appreciated our exchanges. Have a nice day.
