Hi Everyone,
I have a terry strange issue i'm dealing with right now. For about 0.09% of the traffic we get a 400 (Duplicated Header ) Error from Nginx.
I don't really run a very standard setup but i would like to understand what could be the cause of this.
a current traffic flow looks like
Client => DDOS Mitigation(also nginx) = > Nginx Reverse Proxy => Imperva WAF => Haproxy*(SSL Offload) => Nginx (Magento-Stack) 400 error here
On both Nginx servers i have ignore_invalid_headers set to off.
