  mod_rewrite on domain root
  
  I am trying to find the correct mod_rewrite code for the following case:
  domain.de => www.domain.com/de/
  domain.de/... => www.domain.com/...
  www.domain.de => www.domain.com/de/
  www.domain.de/... => www.domain.com/...
  
  domain.com => www.domain.com/en/
  domain.com/... => www.domain.com/...
  www.domain.com => www.domain.com/en/
  www.domain.com/... => www.domain.com/...
  
  so basically
  
  all non-www domains should be redirect to www.
  all uri's ending on .de or .de/ should be redirected to www.domain.com/de/
  but if somebody enters something after the .de/ that should be simply appended to www.domain.com/...
  
  Can anyone think of a clever solution for this? I have been struggling with {REQUEST_URI} and {REQUEST_FILENAME} trying to figure out if the requested URI ends on .de or .de/ but couldn't find a working solution...
  
  A:
  
  Try this:
  RewriteCond %{HTTP_HOST} ^(www\.)?example\.de$
  RewriteRule ^$ http://www.example.com/de/ [L,R=301]
  RewriteCond %{HTTP_HOST} ^(www\.)?example\.de$
  RewriteRule . http://www.example.com%{REQUEST_URI} [L,R=301]
  RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$
  RewriteRule ^$ http://www.example.com/en/ [L,R=301]
  RewriteCond %{HTTP_HOST} ^example\.com$
  RewriteRule . http://www.example.com%{REQUEST_URI} [L,R=301]
