The storage destination of mod rewrite has to be moved. Currently it is not possible to handle different enviroments. The configs should be stored in the folder <clientname>/data/config/<environment>/config.mod_rewrite.php
Implement a behaviour for updating existing mod rewrite configs when a admin runs update mode.
When we use a redirection in a htaccess file like RewriteRule ^products/([^/]*)/index.html$ front_content.php?idart=651&category=$1 [L,QSA]
mod rewrite has to check if there is a idart or idcat variable given by GET or POST. In this cases the given SEO URL in S_SERVER array will be ignored. Currently in this cases Mod Rewrite has a higher priority than given idart and idcat definitions. There is also a check if we were in Backend or not which disables mod rewrite behaviour.
At this position, this check sould be added.
