ReWrite with [P] Proxy

Two servers. example.net, and example.com

On http://example.net, My httpd.conf contains

RewriteEngine On
RewriteRule  ^/felipetest2 http://example.com/webpage [P]

I am getting a 302 Moved, which is pointing to http://example.net/webpage, but should be http://example.com/webpage

What’s going on?

I have control over both .net and .com servers in these examples.
