.htaccess rewrite to another port

Question

I have a joomla setup in my /home/joomla directory. I installed both Apache and Lighttpd i have configured Lighttpd to proxy only static files, and lighttpd is listening on port 81. Now what i want is

whenever request for static files are made, instead of going to

www.domain.com/whatever/bg.jpg

it should redirect to

domain.com:81/whatever/bg.jpg

using .htaccess

also notice that www.domain.com changed to domain.com

please please i need a quick help for it :)

Alright i found out the way :)

RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]
RewriteRule \.(jpg|jpeg|png|gif|css)$ http://domain.com:81/$1 [P,QSA,L]
