[HELP!!!] Can envoy be configured to use a second http/https proxy about envoy HOT 7 CLOSED

@alyssawilk probably understands this.

from envoy.

Envoy can both forward CONNECT request, encapsulate traffic in CONNECT and terminate CONNECT.

@alyssawilk I want to achieve is that all http/https in this pod must go through my clash client proxy service before accessing the target website. , so I want to use EnvoyFilter to achieve it, but I really understand too little about this.

For example, I want to intercept all http/https export traffic of the pod labeled app, and forward this part of the traffic to my clash client proxy server (assuming the address is http://a.b.c.com:40001, supporting HTTP over connect ), but I am a complete novice on envoy-related knowledge. Can you help show me how to implement the code? I will be very grateful~~~

The following is what I learned from some information I searched before:

But it doesn't work. I don't quite understand how to modify it, even though I checked a lot of information.

apologies, but I think you're going to have to play around - I'm unfortunately too overloaded to dig in the way I'd need to to help out.
