# Use the front controller as index file. It serves as a fallback solution when# every other rewrite/redirect fails (e.g. in an aliased environment without# mod_rewrite). Additionally, this reduces the matching process for the# start page (path "/") because otherwise Apache will apply the rewriting rules# to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).DirectoryIndex app.php
