Is it possible to do a mod_rewrite from one url to another without changing what appears in the address bar (ie., I want the base domain to remain static, even though what is being served comes form a different server)?

Example:

Source URL is http://domain1.com/news
Target URL is http://domain2.com/news

I want to render pages from http://domain2.com/news/ but have http://domain1.com/news remain static in the address bar.

Is this possible?

I've got this directive. The pages serve properly, but the URL in the address bar changes (which I don't want to happen):

RewriteRule ^(.*)$ http://domain2.com/news/ [L,NC]
