[support] mod_rewrite

[Jeff Brown]

Hi all,

I have a rewrite rule to send http://jejane.co.za to http://www.jejane.co.za 
  so:

RewriteCond %{HTTP_HOST} ^jejane\.co\.za$ [NC]
RewriteRule ^(.*)$ http://www.jejane.co.za/$1 [L,R=301]

$cookie_domain is set in settings.php; but when I try to login, the  
page just refreshes for the anonymous user.

When I disable the rewrite rule and refresh the page, it works again.

This works fine on other sites!

Any ideas, please?
