I have a web application (confidential client) that has a web route at `/logout` that upon visiting, will `301` redirect the user to `https://keycloak?post_logout_redirect_uri=...&id_token_hint=...`.

At which point the user gets a logout and redirects back to whatever I have passed in the redirect uri … long story short; it works fine.

I am just wondering if this is a Front or Back channel logout. I would suspect “front channel” because I communicate the logout requests between RP and OP via the User Agent… right?

Back-channel would be my backend just sending a HTTP request to the Keycloak directly, without any `301` redirection going on.

This is described in [the spec](https://openid.net/specs/openid-connect-frontchannel-1_0.html#Introduction), just asking for verification.
