Re: Client-Cert Header draft

[Justin Richer <[e-mail]>]

+1 for seeing this adopted and progressing within this group. This is a simple thing that different developers have had to solve for decades and each has solved it in trivially different ways. I would love to see one commonly-accepted way to do this.

TLS terminators aren’t going away any time soon, so I think we should make them at least a bit more manageable.

And that's what brings me here. I also hope to get a little bit of time at one of the upcoming virtual interims to present/discuss the draft.
