Proxy link expandig

Hello,

I have setup a 3-tier test environment of Mattermost with nginx providing the web layer. These are on an internal network without direct internet access.

What we would like is for links entered into the chat to be expanded and for that they would probably need access to the public internet which would mean routing through the corporate proxy.

Is there a recognized way to do this via config, or is as I would guess something nginx will do.

Any examples would be appreciated.

Thanks
