// On 1and1, PHP's directory structure starts with '/homepages'. The
// 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
// Here we fix up the paths to make mode_rewrite work on 1and1 shared hosting.
