We must use an http proxy to get access to the internet. I have set up OpenStack Mitaka, but I cannot find a way to tell Horizon (Dashboard) to use our http proxy for image creation if someone stated a valid url in the UI as image location.I have already created a proxy.sh script in the folder etc/profile.d which exports the variables http_proxy, https_proxy and no_proxy. When I use the glance CLI for image creation, everything is working as expected and the image gets downloaded via the http proxy, but it does not work from within Horizon's UI.

Has someone an idea how to get image download working when Horizon has to use an http proxy?
