.htaccess Domain Alias Redirect

[Faded]

Hello All!

I am having some troubles redirecting traffic using .htaccess.

Basically, I have two domains, of which one is an alias for another, so any requests for

http://www.domain1.com

or

http://www.domain2.com

will end up at

http://www.domain1.com

So, using .htaccess, I am looking for a way to determine if users requested

http://www.domain2.com,

and redirect them to

http://www.domain1.com/directory/file.html

I have unsuccessfully tried variations of the following:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^

http://www\.domain2\.com

[NC]
RewriteRule ^/(.*)

http://www.domain1.com/directory/file.html/$1

[L,R]

Any help is greatly appreciated.

Cheers, F4d3d
