You need to use virtual hosts.  mod_rewrite's first argument accepts a path, second argument accepts a path or URL.  


<pre>
--------
RewriteEngine on
RewriteRule    ^(.*)$    http://www.othersite.com$1
--------
</pre>

This takes a request:

http://example.com/index.php

and parses it, so $1='/index.php'.  

Then serves http://www.othersite.com/index.php

Where's the string 'example.com'?  Nowhere, the regular expression "^(.*)$" sucked in the whole thing.  That's all that is available for mod_rewrite to process.

Now quit trying to be lazy with the 5 minutes it takes to make a new vhost, there's a reason why people get paid for this stuff :)
