You really don't want to do that... think about the following:
http://reverse.proxy/testing/www.google.com/
And any others. Your proxy could be used to launch an attack against a
third party.
You could however use something like:
RewriteRule ^/testing/(servera|serverb|serverc)/(.*)$ http://$1/$2 [P]
Gut you'd need to add ProxyPassReverses in for all combinations!
