Apache AllowEncodedSlashes Not Working

I'm ru开发者_StackOverflownning Apache(XAMPP package) and i'm trying to allow forward slashes in the URI to be able to retrieve parameters sent with encodeURIComponent, so i added the directive

AllowEncodedSlashes On
NameVirtualHost *:80
...

in httpd-vhosts.conf. however i'm still getting 404 error, am i missing something?

Regards.

AllowEncodedSlashes can't be put in the <Directory> tag and have to put in the root level
