Apache redirect full URL with RewriteRule

Question

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?

Apache (or mod_rewrite) might be constructing the "Location:" header line wrong. Add a slash to the rewrite rule:

RewriteCond %{HTTP_HOST} ^foo.domain.com
RewriteRule ^/(.*)$ http://www.domain.com/foo/$1 [R=permanent,L]

When I tried this without the slash, I would get "Location:" header lines that looked something like: http://www.stratigery.com/foo//whatever. I'm not sure that all browsers can handle an extra slash in the URL.
