Required Proxy Modules for OOD/Apache

Get Help
1

Greetings,
We’re running OOD 3.1 in an Apache 2.4 and RHEL 9.4 environment. We would like to limit the number of running httpd modules for security reasons. The 00-proxy.conf file has these modules enabled:
proxy_module
lbmethod_bybusyness_module
lbmethod_byrequests_module
lbmethod_bytraffic_module
lbmethod_heartbeat_module
proxy_ajp_module
proxy_balancer_module
proxy_connect_module
proxy_express_module
proxy_fcgi_module
proxy_fdpass_module
proxy_ftp_module
proxy_http_module
proxy_hcheck_module
proxy_scgi_module
proxy_uwsgi_module
proxy_wstunnel_module

What are the minimum required modules by OOD, and which ones can we disable from that list?

I think you can disable a lot of them. Debian ships apache2 the other way around - disabling a lot of things that you have to specify.

The ansible role is really all I have to go off of because it enables apache2 mods on Debian. Here are the modules we enable on Debian, so you may assume that you can disable everything else.
