There probably are security implications with this, like other apps being able to access authentik's cookies. We should probably mention them in the documentation.

Oh yeah, I had this set when initially testing but it must've gotten removed at some point: 06723cb

Subpath support

[rissson]

Haven't tested it myself, but looks ok. I do wonder what would happen with media files when stored as files though.

[cfradewavecom]

I would like to test this but got image NotFound when using ghcr.io/goauthentik/dev-server:gh-3a176a0024e688cd6b126923b221b3e207314def

Can someone retry pipeline or event better rebase this PR with latest release? Thanks

[kensternberg-authentik]

The Typescript looks fine. A couple of points come to mind: we have three different URLs: internal, another interface, and external. Supporting this feature makes using a browser-based router that much harder, which in turn will make the command palette a... challenge. :-)

[kensternberg-authentik]

This repetition starts to feel like it needs to be, oh, I dunno, a function somewhere. :-)
