Vhost redirect captures request for other (deactivated) vhost

Hi out there! I am an Apache amateur, have learned a lot about Apache configuration but still I am not familiar with the "Redirect" function.
We are hosting 2 domains "perrypedia.de" and "perrypedia.proc.org", the latter is the old domain name that is to be redirected to the new one. Within perrypedia.de, there are two wikis running, test.perrypedia.de and www. perrypedia. de. Also, all requests without SSL shall be redirected to https. To achieve this, I created four config files with a total of five Vhosts. They work perfectly well and stable (... with one exception I'll tell later).

Ubuntu 18.04, Apache 2.4.29

Testwiki, http:

<VirtualHost *:80>
        ServerName test.perrypedia.de
        Redirect 301 "/" "https://test.perrypedia.de/"
</VirtualHost>

Code (markup):

Testwiki, https:

<IfModule mod_ssl.c>
<VirtualHost *:443>
        ServerName test.perrypedia.de
        DocumentRoot /var/www/test
        RewriteEngine on
        RewriteRule ^/?wiki(/.*)?$ %{DOCUMENT_ROOT}/mediawiki/index.php [NE]
        RewriteRule ^/*$ %{DOCUMENT_ROOT}/mediawiki/index.php [NE]
(... a lot more directives: logging, SSL certificate, bandwidth, directory access ...)
</VirtualHost>
</IfModule>

Productive, http:

<VirtualHost *:80>
        ServerName www.perrypedia.de
        ServerAlias perrypedia.de
        ServerAlias www.perrypedia.proc.org
        ServerAlias perrypedia.proc.org
        Redirect 301 "/" "https://www.perrypedia.de/"
</VirtualHost>

        ServerName www.perrypedia.de
        ServerAlias perrypedia.de

        RewriteEngine on
        # add www
        RewriteCond "%{HTTP_HOST}" "!^www\." [NC]
        RewriteCond "%{HTTP_HOST}" "!^$"
        RewriteRule "^/?(.*)"      "https://www.%{HTTP_HOST}/$1" [L,R,NE]
        # Short url
        RewriteRule ^/?wiki(/.*)?$ %{DOCUMENT_ROOT}/mediawiki/index.php [NE]
        # Redirect / to main page
        RewriteRule ^/*$ %{DOCUMENT_ROOT}/mediawiki/index.php [NE]
        # Cache
        RewriteCond %{HTTP_COOKIE} !UserID=
        RewriteCond %{QUERY_STRING} !.
        RewriteCond %{THE_REQUEST} ^GET\x20/wiki/([^\x20/]+)\x20HTTP
        RewriteCond %{DOCUMENT_ROOT}/mediawiki/cache/%1.html -s
        RewriteRule ^wiki/(.+)$ /mediawiki/cache/%1.html [B,L,NS]
(... a lot more directives: logging, SSL certificate, bandwidth, AWStats, directory access ...)
</VirtualHost>
<VirtualHost *:443>
        ServerName www.perrypedia.proc.org
        ServerAlias perrypedia.proc.org
(... SSL ...)
        Redirect 301 "/" "https://www.perrypedia.de"
</VirtualHost>
</IfModule>

The redirects and rewrite-rules are mostly not my invention but put together from several web resources. Nearly everything is fine ... now here's the problem I cannot deal with. When I shut down the productive site (a2dissite prod-http & https), immediately the Testwiki grabs ALL http-requests even that for the productive site. And vice versa (stopping Testwiki leads ALL http-test-URLs to the prod wiki). This seems to happen because of the unspecific Redirect 301 "/" ... I thought the Vhost grabs only URL matching its server name or aliases, but now I am in doubt. I want to learn and understand what I am doing wrong. Anyone having a valuable hint?

 

I requested to delete his post and to delete my profile. I used the "report this post" feature because there is NO contact address, NO administrator, NO ONE responsible for this forum. There is NO WAY to edit or remove a posting, NO WAY to delete my profile, NO WAY to resign or leave this forum. This is stone age.

DIGITAL POINT IS DIGITAL BULLSHIT !!!
