How do i configure a proxy server to be used by remotes in pulp_rpm?

Problem:
Hi,
i’d like to configure a global Proxy server for all plugins, (or at least pulp_rpm) to be used when doing remote connections.

I suceeded if i use the proxy-url parameter during creation of a new “remote”, But without connection times out! (Although the global environemt variable “http_proxy” and “https_proxy” were set!)

Is there no global setting as in pulp2 rpm_importes cfg file /etc/pulp/server/plugins.conf.d/yum_importer.json ?

Thanks for help
Cheers
Andi

Expected outcome:
No need to specify proxy for every single remote!

Pulpcore version:
3.22.3
Pulp plugins installed and their versions:
pulp-rpm 3.19.2

Operating system - distribution and version:
RHEL 9

I do not think this is currently possible.
Maybe file a feature request.
