httpd rewrite or redirect to subdomain

How to achieve
http://(www.)domain.com.br/vi/{N}.htm
redirect or rewrite to
http://web.domain.com.br/vi/{N}.htm
? I try for very long time and not right effect

 

RewriteCond %{HTTP_HOST} ^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://web.domain.com/$1 [R=301,L]

 

Edit:
Looking for all other URI equal(!), how to redirect only URI like eg

http://domain.com.br/vi/9975.htm

Code (markup):

to

http://web.domain.com.br/vi/9975.htm

Code (markup):

Tried all these

Redirect /abc2.html http://web.domain.com.br [R=301,L]
RedirectMatch permanent ^/anything/(.*)$ http://web.domain.com.br/$1
RedirectMatch permanent ^/vi/(.*)$ http://web.domain.com.br/vi/$1
RedirectMatch permanent ^/vi/?([0-9]+)\.htm$ http://web.domain.com.br/vi/$
RewriteCond %{HTTP_HOST} ^www.domain.com.br/vi/$ [NC]
RewriteRule ^(.*)$ http://web.domain.com.br/vi/$1 [R=301,L]

Code (markup):

 

i think .htaccess file can easy to resolve the problem. the code:

RewriteCond %{HTTP_HOST} ^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://web.domain.com/$1 [R=301,L]

 

I too think that looks right. Hence trying this full set and reporting back how it goes while you may inspect www.montao.com.br/vi/{N}.htm still won't redirect to web...accordingly

RewriteRule ^/vi/?([0-9]+)\.htm$ /Market/vi.do?id=$1 [PT,L]
RewriteRule ^/li /Market/list.do [QSA,PT,L]
RewriteRule ^/vi/locations.jsp /Market/locations.jsp [PT,L]
Redirect /abc2.html http://web.montao.com.br [R=301,L]
RedirectMatch permanent ^/anything/(.*)$ http://web.montao.com.br/$1
RedirectMatch permanent ^/vi/(.*)$ http://web.montao.com.br/vi/$1
RedirectMatch permanent ^/vi/?([0-9]+)\.htm$ http://web.montao.com.br/vi/$
RewriteCond %{HTTP_HOST} ^www.montao.com.br/vi/$ [NC]
RewriteRule ^(.*)$ http://web.montao.com.br/vi/$1 [R=301,L]

Code (markup):

 

All that is missing to catch is the dot. Hence my wonder if the whole wanted effect can be done with RedirectMatch only since nearly the same redirect is doable already ie

http://montao.com.br/vi/asd

Code (markup):

redirects to

http://web.montao.com.br/vi/asd

Code (markup):

according to

RedirectMatch permanent ^/vi/(.*)$ http://web.montao.com.br/vi/$1

Code (markup):

Now clearly what I want is

http://montao.com.br/vi/{N}.htm

Code (markup):

redirects to

http://web.montao.com.br/vi/{N].htm

Code (markup):

ie just add a subdomain to one dynamic uri. This should be easy or why not?
