Symfony .htaccess adding rule for app_MYNAME.php - apache

Question

i want to add another app_MYNAME.php in the web folder.
This file is nearly identical to the app.php.
The only difference is this entry:
$kernel = new AppKernel('MYKERNELNAME', false);
I want to load different configuration files with these method.
When i type in the browser:
domain.de/app_MYNAME.php/VALUE
all is fine.
Now i want to hide the app_MYNAME.php. The Result should look like:
domain.de/VALUE
The second step is the redirecting. When someone type in the browser:
domain.de/MYNAME/VALUE
it should be redirected to:
domain.de/app_MYNAME.php/VALUE
I only get a 404 or a misconfigured message.
At the end i need 3 app_MYNAME.php files (app_MYNAME1.php, app_MYNAME2.php, app_MYNAME3.php).
I hope someone could explain me, what to put in the .htaccess file.
Here is my .htaccess file:
DirectoryIndex app.php
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
RewriteCond %{HTTP:Authorization} .
RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^app\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
RewriteRule ^ %{ENV:BASE}/app.php [L]
</IfModule>
<IfModule !mod_rewrite.c>
<IfModule mod_alias.c>
RedirectMatch 302 ^/$ /app.php/
</IfModule>
</IfModule>

Answer 1

Try with a configuration that looks like this in your .htaccess file :
<IfModule mod_rewrite.c>
RewriteEngine On
# ... Your other stuff
# RewriteRule ^(.*)$ /app.php [QSA,L]
RewriteRule ^(.*)$ /app_MYNAME.php [QSA,L]
</IfModule>
Also, make sure that your nginx/apache host file is pointing to the web directory of your Symfony project.

Answer 2

Try this :
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app_MYNAME.php [QSA,L]
Maybe all app.php could convert to app_MYNAME.php in your htaccess
