redirect question

[Masali]

Hello!

i have a htaccess problem... I want to redirect all traffic in one of my webfolders, even if file exists or not.

The problem is that i want to redirect traffic to one place if not from a special referer, then i want to redirect traffic to another place.

Say, i access

http://www.mydomain.com/folder/something.html

from google.com listing i want it to redirect to

http://www.test1.com,

and if

http://www.mydomain.com/folder/something.html

is accessed from anywhere else, or no referer i want it to be redirected to

http://www.test2.com

How can i do this?

Best regards

Masali
