The following .htaccess file does not work:

SSLrequireSSL

RewriteEngine on
RewriteCond %{HTTP_HOST} !^secure\.neuralfutures\.com [NC]
RewriteRule (.*) - [F]

I'm trying to prevent access to anything but "https://secure.neuralfutures.com/docs/", i.e. "https://www.neuralfutures.com/docs/" will fail.

I also seem to be running into caching issues: if I upload the new .htaccess with CuteFTP, then do a file refresh in FireFox, it doesn't seem to have any effect on the output at all. I can tell this because if I comment out SSLrequireSSL, it still disallows a http:// request.
