Yeah, my thought exactly. If your relying on a rewrite rule for
securtiy, you're in for some problems. Apache offers other messures
for this, as PmWiki makes use of. The question is: What does Apache do
if the check for existance of a file returns permission
denied/forbidden. Does the Apache error page get returned (which could
be overriden with another line in .htaccess) or does it run the
rewrite rule? I gotta run, so I doen't have time to test it now. Maybe
