We have a site I'll call acme.com. Most of the time you see http://www.acme.com and sometimes we redirect you to https://www.acme.com.

We want to redirect anyone going to http://acme.com or http://*.acme.com to http://www.acme.com, and the same for https. (It's mainly to avoid the alert you get if you go to https://acme.com instead of https://www.acme.com)

Our vhost file is at the end of the post. It works nicely except for one strange behavior:

It's this last result I can't fathom. I've tried a lot of trial and error solutions from Google & Stack Overflow but nothing seems to change it. Even if we swap the order of the configurations (so that 443 is before 80) it still redirects https://foo.acme.com to http://www.acme.com

We are running Apache/2.2.12 on Ubuntu.

Here's the configuration file:

<VirtualHost *:80>
    ServerName www.acme.com
    ServerAlias acme.com *.acme.com
    ServerSignature On
    DocumentRoot /var/www/acme.com/public
    RailsEnv 'production'
    PassengerHighPerformance on
    <Directory /var/www/acme.com/public>
         AllowOverride all
         Options -MultiViews
    </Directory>
    SSLEngine Off
    CustomLog /var/log/apache2/acme.log combined
    ErrorLog /var/log/apache2/acme-error.log
    # Possible values include: debug, info, notice, warn, error, crit, alert, emerg.
    LogLevel warn
    RewriteEngine On
    RewriteCond %{HTTPS} off
    RewriteCond %{HTTP_HOST} ^[^\./]+\.[^\./]+$ 
    RewriteRule ^/(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
</VirtualHost>

<VirtualHost *:443>
    ServerName www.acme.com
    ServerAlias acme.com *.acome.com 
    DocumentRoot /var/www/acme.com/public
    RailsEnv 'production'
    PassengerHighPerformance on
    <Directory /var/www/acme.com/public>
         AllowOverride all
         Options -MultiViews
    </Directory>
    SSLCertificateFile /etc/ssl/certs/www.acme.com.crt
    SSLCertificateKeyFile /etc/ssl/private/acme.com.private.key
    SSLCACertificateFile /etc/ssl/certs/EV_intermediate.crt
    SSLEngine On
    CustomLog /var/log/apache2/ssl-acme.log "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"
    ErrorLog /var/log/apache2/ssl-acme-error.log
    # Possible values include: debug, info, notice, warn, error, crit, alert, emerg.
    LogLevel warn
    RewriteEngine On
    RewriteCond %{HTTPS} on
    RewriteCond %{HTTP_HOST} ^[^\./]+\.[^\./]+$ 
    RewriteRule ^/(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L]
</VirtualHost>
