.htaccess / pretty urls / mod_rewrite problem?

I have played around a bit to manage pretty-urls on my page, but I've seem to hit some kind of snag - which I can't seem to google my way out of.

I have a rule in .htaccess like this:

Options +FollowSymlinks
RewriteEngine On
RewriteRule ^magic http://www.mydomain.com/forum/viewforum.php?f=22
RewriteRule ^([a-z]+)$ /$1/ [R]
RewriteRule ^([a-z]+)/$ http://www.mydomain.com/index.php?page=$1

PHP:

This works just fine - if I write something like: http://www.mydomain.com/about it correctly redirects to http://www.mydomain.com/index.php?page=about

The problem is, I would like to keep the http://www.mydomain.com/about url in the browsers address bar - as it is now it shows the index.php?page=about instead - I thought the rewrite-rule would change this? Am I doing something wrong, or have I forgotten something?

 

try removing the domain name and just keep the page

Thanks! Stupid mistake, but once you've started staring yourself blind on your own code... +rep added
