Client IP on App Platform


Firstly thanks for all the great community resources here 👍

I’ve been testing out the App Platform with a Docker container that hosts an Apache server. I was wondering what would be the correct way to configure it such that it reports the correct client IP as opposed to the load balancer IPs (I’m assuming that’s the IP I’m seeing)?

I read through this related question which was really useful.

From a quick test, I can see the X-Forwarded-For and DO-Connecting-IP are populated in the headers and contain the client IP.

Setting RemoteIPHeader X-Forwarded-For on it’s own doesn’t do the trick sadly. Reading further through the docs of mode_remoteip it seems in order for this work a list of trusted proxy IP addresses is needed.

e.g. RemoteIPTrustedProxy

Is there a stable set hostnames or IP ranges that can be used? Is there perhaps a more correct way of achieving this on App Platform?

Hey there!

The DO_Connecting-IP header should actually contain the connecting IP address of the client. This header would be used to obtain that information.


Hope it helps! Nate

In case anyone that is using php on the app platform finds this

This server var is prefixed with HTTP_
