OK - but now the URL is outside the authentication realm so the browser
sends the request without credentials, so it triggers the rewrite and
you go round the loop again. And again. And againnnnnn.....
I don't think you can do this the way you want without using
session-handling (ie, cookies) which is beyond the scope of mod_auth. A
workaround would be to symlink /protected/index.php back to /index.php
so that when you hit the authenticated directory you really do execute
/protected/index.php (then you just drop all the rewrite rules from the
directory container).
