Hello @aspires, thank for the answer.
I actually created a ticket after realizing that’s actually ongoing when ngwaf is enabled.
As the agent is making the request to the backend, i assume the VCL timeouts, or the host configured timeouts are ignored.
Hope there’s a feedback from CSOC, because that’s the second severe limitation we’re facing after the one i mentioned at Self Signed certificates in backend and NG-WAF - General - Fastly Community
