It should not work on another server without mod_proxy compiled
Thats from oneandone (work host).
What i don't understand is if rewrite works on my own host without mod_proxy, why would oneandone needs it for the rewritten url to stay in the address bar. The whole point of mod_rewrite for me was to disguise long dynamic url's with a shorter version. I can't do that if the rewritten url redirects you back to the long one when used.
Afaik mod_rewrite can work perfectly without mod_proxy (otherwise it would have been clearly mentionned in the documentation :p And i can't think of a configuration where it would be required... Perhaps with a reverse proxy.. But i still have to think about that specific situation :p)
