htaccess 301 Umleitungen funktionieren nicht

Hallo,
nachdem ich meine Inhalte mit Meta Model umstrukturiert habe, möchte ich einige Seiten auf die neuen Inhalte umleiten. Leider funktieoniert eine 301 weiterleitung in der htaccess Datei nicht. Meine htaccess Datei sieht wie folgt aus:

Code:

---

<IfModule mod_headers.c>
    # Allow access from all domains for webfonts (see contao/core-bundle#528)
    <FilesMatch "\.(ttf|ttc|otf|eot|woff2?|font\.css)$">
        Header set Access-Control-Allow-Origin "*"
    </FilesMatch>
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On
        Redirect 301 /allgaier-a22 http://schlepperblog.de/detail/traktor/allgaier-a22

    # Determine the RewriteBase automatically and set it as environment variable.
    # If you are using Apache aliases to do mass virtual hosting or installed the
    # project in a subdirectory, the base path will be prepended to allow proper
    # resolution of the app.php file and to redirect to the correct URI. It will
    # work in environments without path prefix as well, providing a safe, one-size
    # fits all solution. But as you do not need it in this case, you can comment
    # the following 2 lines to eliminate the overhead.
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    # Sets the HTTP_AUTHORIZATION header removed by Apache
    RewriteCond %{HTTP:Authorization} .
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    # Uncomment the following lines to remove "www." from the domain:

    # Redirect to URI without front controller to prevent duplicate content
    # (with and without `/app.php`). Only do this redirect on the initial
    # rewrite by Apache and not on subsequent cycles. Otherwise we would get an
    # endless redirect loop (request -> rewrite to front controller ->
    # redirect -> request -> ...).
    # So in case you get a "too many redirects" error or you always get redirected
    # to the start page because your Apache does not expose the REDIRECT_STATUS
    # environment variable, you have 2 choices:
    # - disable this feature by commenting the following 2 lines or
    # - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
    #  following RewriteCond (best solution)
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]

    # If the requested filename exists, simply serve it.
    # We only want to let Apache serve files and not directories.
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ - [L]
    # Rewrite old .html
    RewriteRule ^(.*)\.html$ /$1 [L,R=301]
    # Rewrite old .html URLs (app/config/config.yml -> contao: url_suffix: '')
    RewriteRule ^(.*)\.html$ /$1 [L,R=301]
    # Rewrite all other queries to the front controller.
    RewriteRule ^ %{ENV:BASE}/app.php [L]

</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        # When mod_rewrite is not available, we instruct a temporary redirect of
        # the start page to the front controller explicitly so that the website
        # and the generated links can still be used.
        RedirectMatch 302 ^/$ /app.php/
        # RedirectTemp cannot be used instead
    </IfModule>
</IfModule>
