Robert Metzger commented on FLINK-29363:
----------------------------------------

So the setup would be that there's an authenticating proxy between the Flink 
Web UI and Flink's REST API.
The problem is currently that if a REST API call fails, the UI will just break, 
instead of redirecting to another page.

How would we be able to distinguish between auth errors and generic errors? I 
guess based on the HTTP error codes?.
One problem I see is that this setting is purely used in the UI, so we need a 
way of forwarding a "global setting" to the UI ... but I guess that's solvable.

> Allow web ui to fully redirect to other page

> In a streaming platform system, web ui usually integrates with internal 
> authentication and authorization system. Given the validation failed, the 
> request needs to be redirected to a landing page. It does't work for AJAX 
> request. It will be great to have the web ui configurable to allow auto full 
> redirect.
