Satellite 6: Importing repositories through an HTTP proxy?

Folks,
The Pulp yum importer proxy settings don't seem to be working to allow me to import Redhat content into my Satellite 6 server.

I've set the /etc/pulp/server/plugins.conf.d/yum_importer.json file as follows:
{
"proxy_host": "proxy.college.edu",

"proxy_port": 8080,

"proxy_username": "",
"proxy_password": ""

}

Please let me know how I should be setting Satellite 6 up to sync content from Redhat through a standard bluecoat HTTP/S proxy.

For the Hatters here, it should be noted that the latest Install Guide makes no mention of making any of the install / deploy process proxy aware. This is problematic for most larger companies I'd wager, and the documentation should probably be amended.

Thanks!
