Can anyone direct me to any documentation on configuring an http proxy in Magento? Our network environment now requires all web requests to go through a proxy. I can not find any details on configuring this in Magento. I have configured the proxy on the OS level and that is working now problem. Git and composer work as well. I'm unclear on whether there is any other configuration I must perform for Magento to use the proxy for all external web requests.
With the proxy required, I noticed that the admin page timeouts when using a custom theme like the Pearl theme from WeltPixel. My network team sees that it is trying to reach out to license.weltpixel.com. So, Magento isn't using the proxy configured on the host.
