Well, not really :-) It might work in devstack, but it really breaks TripleO.
We currently configure Apache with the same template of configuration
for Nova, Cinder, Keystone, Ceilometer, Aodh, Gnocchi, Mistral, (...)
and Ironic.
Ironic is the only service that looks unstable when deploying with Apache.

Please look at Ironic vhost:
https://paste.fedoraproject.org/400663/02264641/

And Ironic configuration file:
ironic: https://paste.fedoraproject.org/400666/26543147
ironic-inspector: https://paste.fedoraproject.org/400665/70226518

Do you see something not conventional?

I see that the reverted patch touches rabbit config somehow:
Class['::rabbitmq'] -> Service['httpd']

And the bug report has lots of errors about rabbit messages timing out.

Sounds related; what does that line do?

I haven't dug to see what the puppet modules are doing, but we do have
documentation around setting up the ironic-api service to run behind
Apache with mod_wsgi:
http://docs.openstack.org/developer/ironic/deploy/install-guide.html#configuring-ironic-api-behind-mod-wsgi

I've followed the instructions and got it working in an local
environment here (logs: http://paste.openstack.org/show/547736/)

Hope that helps,
Lucas

I hit a similar issue earlier this year when we tried deploying mistral
with apache.  https://bugs.launchpad.net/mistral/+bug/1581649
