htaccess redirect

[toString]

I'm using this so that if any old links that are around go to the 'newer' address of gallery.dom1.

RedirectMatch permanent ^/gallery/(.*)?$ http://gallery.dom1.com/$1

However I have an addon domain and I want to use a subdir called gallery on that, such as: dom2.com/gallery/

However the redirect kicks in and sends me to gallery.dom1.com!

How can I change the redirect so that it only works for dom1, and not dom2. IF that makes sense!
Thanks for any help

Where have you put the .htaccess file?

EDIT- nevermind; I misread. As the addon domain is essentially a subdirectory, make sure the rule is only applying to the top-level dir.

http://httpd.apache.org/docs/1.3/mod/core.html#directory should do it.

Thanks for that, but I get a 500 error from this:

<Directory /home/me/public_html> (or public_html/gallery)
RedirectMatch permanent ^/gallery/(.*)?$ http://gallery.dom1.com/$1
</Directory>

Also it says this:
<Directory> and </Directory> are used to enclose a group of directives which will apply only to the named directory and sub-directories of that directory
- Doesn't that mean that it would work for my dom2 subdirectory too?
