  <pre><code># 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
  
  &lt;IfModule mod_rewrite.c&gt;
      RewriteEngine On
  
      # 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]
  
      # 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 -&gt; rewrite to front controller -&gt;
      # redirect -&gt; request -&gt; ...).
      # 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 &gt;= 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}/$2 [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 all other queries to the front controller.
      RewriteRule .? %{ENV:BASE}/app.php [L]
  &lt;/IfModule&gt;
  
  &lt;IfModule !mod_rewrite.c&gt;
      &lt;IfModule mod_alias.c&gt;
          # 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
      &lt;/IfModule&gt;
