Does not work over web proxy/firewall?

[mouse07410]

I'm trying to use kramdown-rfc from behind a corporate firewall that requires apps to go through the HTTP_PROXY host to reach web sites outside the perimeter.

It looks like net-http-persistent fails to use HTTP_PROXY:

This problem is brought up in https://github.com/martinthomson/internet-draft-template/issues/11

Help is appreciated.

net-http-persistent supports proxies just fine, https://github.com/rubygems/rubygems/blob/f90de8bdafedde5c106963f149a51dddbbd73aee/bundler/lib/bundler/vendor/net-http-persistent/lib/net/http/persistent.rb#L784

It's quite confusing to work out what you're running, I think it's https://github.com/martinthomson/i-d-template/blob/cf4cd05892ae39c481f270cc23a67fa4b54ac2f2/main.mk#L76. There's nothing there that suggests environment variables are being stripped, have you set it via export HTTP_PROXY=https://your.corp.firewall.setting/?

I'm trying to format an IETF RFC (Internet Draft, to be precise), using Martin Thompson's stuff. The platform is MacOS Monterey.

Yes, I have HTTP_PROXY and HTTPS_PROXY set appropriately. Other apps, like wget and curl (and, pretty much, everything else) seem to have no problem going over proxy to access our retrieve stuff from the "outside".
