Redirecting urls with mediawiki

Hi everyone,

I’ve recently changed my default mediawiki urls to short urls eg.

to just

Is there a way users can be redirected to my moved articles because when they enter an old bookmarked page, it goes to a blank page with the url (wiki with a capital W in the url for some reason). I’m assuming here I’ll have to tinker with the .htaccess file and perhaps the localsettings.php file to get the correct redirection to work. Mediawiki is installed in directory w btw. Advice in fixing the urls appreciated.
