Redirect based on response code

[eadwu]

Hey, I set up a SecurityPolicy that correctly returns/allows urls. I want to redirect 401 to a login page, from what I could find for routes, I could find a way to match the response. (I see redirect filter and response header)

there's no first class API for this yet in Envoy Gateway

you can achieve this by configuring this filter https://www.envoyproxy.io/docs/envoy/latest/configuration/http/http_filters/custom_response_filter#redirect-policy in Envoy directly using https://gateway.envoyproxy.io/docs/tasks/extensibility/envoy-patch-policy/

In the future it could be added into #1400
