how to 301 redirect from subdirectory to new domain????

i have a problem to redirect from subdirectory to new domain??
i do the following

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^newdomain.com [nc]
rewriterule ^(.*)$ http://www.olddomain.com/subdirectory/$1 [r=301,nc]

Redirect permanent / http://www.newdomain.com/

Code (markup):

it redirects from

http://www.olddomain.com/subdirectory

Code (markup):

to

http://www.newdomain.com/subdirectory

Code (markup):

i want the redirection to the following

http://www.newdomain.com

Code (markup):

i want the redirection to the home page not from a subdirectory to a subdirectory

 

The following code will probably work for you

RedirectMatch 301 /subdirectory(.*) http://newdomain.com/$1

Code (markup):

 

really thank you it works like a charm
i did add only that code at the .htaccess

RedirectMatch 301 /subdirectory(.*) http://newdomain.com/$1

Code (markup):

don't you think i should add something extra
like that at the beging of the file...

Options +FollowSymlinks
RewriteEngine on

Code (markup):

sorry i have very little knowledge about .htaccess file configuration

 

just 1 modification to your code
you must remove the backslash from the new domain
instead to be like that

RedirectMatch 301 /subdirectory(.*) http://newdomain.com/$1

Code (markup):

to be like taht

RedirectMatch 301 /subdirectory(.*) http://newdomain.com$1

Code (markup):

becasue it adds one more slash after the domain name
anyway I'm very thankful for your help
