Apache redirect full URL with RewriteRule

I have a redirect problem with 'RewriteRule', i have this in mt .htaccess: RewriteCond %{HTTP_HOST} ^foo.domain.com RewriteRule ^(.*)$ http://www.domain.com/foo/$1 [R=permanent,L] If i go to foo.domain.com redirect to www.domain.com/foo/ and it's ok, instead i go to foo.domain.com/bar i have an error, must go to www.domain.com/foo/bar. Where is error?
