Add Support for Step 4 (ACME Challenge) on https / different Ports about gethttpsforfree

[alariel]

If you direct all traffic from the unencrypted (Port 80) instance to https (via 301 status) it just works, at least for me. Maybe one can add a specific redirect for the checked files/directories...

For Apache, i simply did Redirect 301 "/" "https://www.domain.de/" in the <VirtualHost *:80>- part of the config.

A configurable part would be nice to have, though... but i think it's limited to what LE implements/already has implemented...

I would gladly do that, but due to regulations the Web Servers are only available on 443 and not even listening on Port 80 (not even for redirects to 443).

I would really appreciate this too. If I want to verify something to be hosted on my home Internet from my home Internet, I need to be able to specify a different port. My ISP blocks incoming port 80 (not 443, interestingly).

edit: Now that I've said this, I wonder if gethttpsforfree is really the project to be asking for this feature. Since fumbling around last night with this, I bought a cheap VPS and have it temporarily change the DNS record, do webroot auth, then change the DNS record back.

DVSNI would be a big pain to implement in a user-friendly manner to this website, so I don't plan to do it. Would be happy to be impressed by a good pull request, though.

+1 for this feature, this would be massively useful for using with django-zappa, as we have no ability to serve over HTTP.

A dropdown with a choice between HTTP and HTTPS would suffice for our purposes, and be MASSIVELY helpful!
