Enabling send_proxy_v2 to see actual client IP instead of proxy IP

[xtrusia]

Hello

Currently, there is no setup related to send_proxy_v2, a customer requested they would like to see real client IP instead of proxy IP in keystone.log

I've researched a bit about this and we need to put this[1]

But it only affects under ssl environment, so I would like to ask how I can enable module for apache2 remoteip

Do I need to create another context for like ApacheContext? or I can use WSGIWorkerConfigContext?

Thanks so much in advance.
