@tcoupin I noticed there are merged conflicts (probably due to use merging PR #8665). Can you please resolve them? Thanks!

[tcoupin]

This PR is now outdated since #8665 add support for http.
I will close this PR and open a new one based on work done by @kcondon in #8665

(keep this open until I create the new...)

Hey @tcoupin, this PR slipped through the cracks for me. This is very much related to my post to the Google Group.

As this is something we'd really need, I'd volunteer to help out if you want.

Thanks you @poikilotherm for your help.
@pdurbin I made this MR #8866
