proxy configuration

[yannski]

1. If a proxy configuration exists on the system, it should be used
2. Even if it exists, it should be possible to bypass it
3. If a proxy configuration does NOT exist on the system, it should be possible to define one

Not sure about 3

Using a HTTP proxy is already possible with the three following env variable: HTTP_PROXY, HTTPS_PROXY, NO_PROXY. Did you think about something else than that?

[yannski]

will it work with HTTP_PORT and a socks URI? At least those variable should be mentionned in the doc.

[yannski]

BTW, aren't the variables named HTTP_PROXY and HTTPS_PROXY?

[EtienneM]

Sorry it was a typo in my message... Variables are HTTP_PROXY and HTTPS_PROXY.

Usage of these variables is in the doc https://doc.scalingo.com/platform/cli/features

Regarding SOCKS5, I just successfully used the HTTP_PROXY variable with a local SOCKS5 proxy. I asked our customer to also test this in order to confirm it works.
