.htaccess - How can I redirect to a different domain without changing the URL in the address bar?

Question

I want to redirect from:

domain1.com/photos

To:

domain2.com/photos

I want the URL in the address bar to still read:

domain1.com/photos

Is there a way to do this using only .htaccess?

Note:

My .htaccess file for domain1.com is currently completely blank.

No, there isn't a way to do this with .htaccess. Doing so would present a glaring security hole - imagine someone doing this with a bank's website!
