Drupal Multi Site Folder structure I have a simple question.

I am trying to create a folder inside the Drupal installation that will not be shared to all the multi-sites.

For example:


  www.mydomain.com/xxx
  
  www.anotherdomain.com/xxx


I need this two folders of xxx should go to different path.

How can I achieve that?

I tried to create a new folder in Drupal root folder, but like this all the domains familiar with the same contents.

Thanks for the help.
To extend @Pierre.Vriens answer , you could then add a rewrite rule to make the urls a bit nicer

assumptions


you've got public files set up
you've got a url 'normalisation' (either symlinks in files directory or 301s)

RewriteEngine On 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /sites/%{HTTP_HOST}/files/$1 [L]



in your host will take

http://www.example.com/filename.pdf


and rewrite it to

http://www.example.com/sites/www.example.com/files/filename.pdf


what do i mean by url normalisation ?
well, if you can get example.com - then you'll get a 404 - as the folder in the sites directory is www.example.com

an easy solution is to use symlinks in the sites directory, or to use 301 redirects

to use symlinks, assume you have 

sites/www.example.com


you could then create a symlink to it as follows

ln -s www.example.com example.com


this would create a symbolic link from 

sites/example.com


to the www.example.com folder. this means that both www.example.com, and example.com would be found when the rewrite rule runs
