IIS Server - Redirecting URL on another server for Challenges

Hi, My letsencrypt certificates are managed by one single server. which means, that all other servers should redirect ACME checking requests to this ssl management server. is that possible? how should I do that? 301?rewrite?

thanks for your answers.

Yes, that will work. :smile: Let’s Encrypt will follow 301 redirects. And 302 redirects. And probably some other redirect codes like 307, but i haven’t checked.

I redirect with IIS (sorry), and redirect seams do not work. so, I used rewrite, with following regex syntax:

^(.welll-known)/(acme-challenge)/([-_0-9a-zA-Z]+)

and rewrited url

http://LE-server-unix.domaine.com/{R:1}/{R:2}/{R:3}

they may have a better way to do that, but I didn’t them. hope that would useful for someone else.
