Apache redirect problem: redirects with escaped / don"t work.

..htaccess:
RewriteEngine On
RewriteRule .* http://www.alltheweb.com [R]

It does the redirect for any url I give it, except a url that contains
'%2F'. That's the escape for /

For example:

http://www.mysite.com/%2F
http://www.mysite.com/wrwrgwr/gwrgw/wefwrg%2Fwrgwrg

Don't redirect. If the url has the %2F in it, apache gives a 404
rather than redirecting. Why? Apache bug?
