		// Apache directory structure has an extra '/kunden' before it.
		// Also 1and1 does not support the %{DOCUMENT_ROOT} variable in
		// .htaccess files.
		// This prevents the $inst_root from being calculated correctly and
		// means that the $apache_root is wrong.
		//
		// e.g. This is an example of how Apache and PHP see the directory
		// structure on	1and1:
		// Apache: /kunden/homepages/xx/dxxxxxxxx/htdocs/site1/index.html
		// PHP:           /homepages/xx/dxxxxxxxx/htdocs/site1/index.html
