I believe this may be a bug with httpbin. Firstly, it seems that you are sending the wrong header - it should be `x-forwarded-for`, not `x_forwarded_for`. However, it appears that httpbin is still able to process the `x_forwarded_for` header for the sake of compatibility. It seems possible that there is a bug related to this compatibility feature. As a solution, you could try the following: ``` curl http://httpbin.org/anything -H "x-forwarded-for: 1.2.3.111" -v -H 'x_forwarded_for: 1.1.1.1' ``` Send request without to APISIX. And you will get the same result below: ``` * Trying 54.173.69.67:80... * Connected to httpbin.org (54.173.69.67) port 80 (#0) > GET /anything HTTP/1.1 > Host: httpbin.org > User-Agent: curl/7.74.0 > Accept: */* > x-forwarded-for: 1.2.3.111 > x_forwarded_for: 1.1.1.1 > * Mark bundle as not supporting multiuse < HTTP/1.1 200 OK < Date: Wed, 17 May 2023 09:10:57 GMT < Content-Type: application/json < Content-Length: 361 < Connection: keep-alive < Server: gunicorn/19.9.0 < Access-Control-Allow-Origin: * < Access-Control-Allow-Credentials: true < { "args": {}, "data": "", "files": {}, "form": {}, "headers": { "Accept": "*/*", "Host": "httpbin.org", "User-Agent": "curl/7.74.0", "X-Amzn-Trace-Id": "Root=1-64649a1f-23d29ac7700c8fc15eac7054" }, "json": null, "method": "GET", "origin": "1.2.3.111, 61.232.56.241,1.1.1.1", "url": "http://httpbin.org/anything"; } ``` -- This is an automated message from the Apache Git Service.
