Redirect entire VHost to HTTPS on same domain

Question

I have a vhost that accepts all domains and subdomains from 4 top domain names, e.g. example.com, example.org, three.example.co.uk etc.

I want the entire VHost to redirect to the exact same URL as requested, but HTTPS.

I know of this:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias *.all *.other *.domains
    Redirect permanent / https://example.com/
</VirtualHost>

but that won't work for subdomains, because explicit target URL.

It's so easy in nginx:

return 301 https://$host$request_uri;

so I thought Apache would have a thing for that, and it sort-of does, but this doesn't work (no Apache error, just broken redirect):

Redirect permanent / https://%{HTTP_HOST}/

Is there any way to use a domain/host variable? Bonus points for not using RewriteRule!

Answer 1

Answer in Apache SSL New Domain Redirect is good enough. (Didn't see that one while typing question.)

Solution:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias *.example.com etc
    RewriteEngine on
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</VirtualHost>

Using %{HTTP_HOST} in target URL seems to work fine with Apache 2.4.

Any method without rewriting, like nginx does? Or not worth it?
