Improve behavior after Concourse logout

[LiliVideva]

Background

As an SAP employee working with multiple Concourse instances (as stakeholder of Concourse), I have experienced multiple times the following situations:

1. After being logged out of a Concourse instance (where the login happens via Cloud Foundry) and attempting to log in again (via CF) I receive invalid state token as an error. Once refreshing the page, and going through the login flow again, I am able to finally log in.
2. Concourse does not remember my location (i.e. not stateful) before it logged me out, so after logging in again I am always navigated to the default page.
3. If I had multiple Browser tabs open showing the same Concourse instance just different jobs/pipelines and I got logged out, after I login to Concourse via one of the tabs again, sometimes Concourse notices that in the other tabs (and sends me to the default page) and sometimes it doesn't.

Expectation

I would expect that Concourse is able to remember the state of my session before it logged me out and attempt to get me in exactly there once I log in again. As well, a behavior similar to how GitHub does it with the multiple tabs open and then one being logged out (i.e. one logs in in one of the tabs and on the others just get something like "you logged in somewhere else, please refresh the page") would be highly appreciated. Last but not least, the bug (from my PoV) with the invalid state token error should also be mitigated (might be specific to the CF login flow, I don't know).

Hi @LiliVideva, I think that behavior was fixed by #9387, which was released with version 8.1.0

Immediately thought of that issue was well. Let us know what Concourse version you're on to confirm if it's the same problem. Very likely is though.

Hi @IvanChalukov , @taylorsilva ,
Apologies for my late response! I was observing the behavior on the Concourse in the CF EU12 region which is currently on v8.0.1. So, I would in this case wait until this Concourse is updated and report back to you whether the issues persist.
