Your server is apparently doing exactly what you told it to do.

How is mod_rewrite supposed to determine the difference between a URL that you *do* want to redirect, and one that you *do not* want to redirect? In general, mod_rewrite can only act based on information received in the HTTP request from the client. So what are the differences between these two kinds of URLs?

By the way, this is not instant messaging. The number of requests here is relatively high, and the number of contributors is relatively low. Also, please be aware that many of us are in different time zones. Please allow some time for replies.

i just want to make

http://example.com/vb/whatever
goes to
http://vb.example.com/whatever

so that

http://example.com/vb/xyz
goes to
http://vb.example.com/xyz

and

http://example.com/vb/aaa

Then all you need is to capture and use the requested URL-path (as $1) in the substitution URL:

RewriteEngine On
Options +FollowSymlinks
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com [NC]
RewriteRule [b]^(.*)$[/b] http://vb.example.co[b]m/$1[/b] [R=301,L]

Or depending on where the .htaccess file containing this code is located, you may need:

RewriteEngine On
Options +FollowSymlinks
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com [NC]
RewriteRule ^vb/(.*)$ http://vb.example.com/$1 [R=301,L]
