http://www.baitona.net/forum03092011/106397-post1.html

in your folder called "forum03092011" cant you create a .htaccess file redirect and add:
RewriteEngine On
RewriteRule (.*) http://www.baitona.net/forum/$1 [L,R=301]

??

thanks Jaycob,
that code work as i have tried it before

howerver it means that the folder "forum03092011" needs to be present all time as it hosts the .htaccess file!!
My questions is what is the way/line i can modify in the root .htaccess in "www.baitona.net"
to do the redirect perminantly , and the folder forum03092011 can be deleted
