Generic Forward Auth Pattern / Policy

[OCram85]

Hey folks,
I'm just evaluation authentic for a special use-case:

I'm hosting multiple user individual applications where I would like to use forward auth. For Example: User individual VSCode instances.

Is there a way to create some generic kind of Application / Provider + Policy to achieve this scenario?

Applications:

• https://vscode-<userA>.mydomain.com
• https://vscode-<userB>.mydomain.com
• https://vscode-<userC>.mydomain.com

Policy:

• userA can access only his instance.
• userB can access only his instance.
• userC can access only his instance.
