With MediaWiki installed in the root of the webserver, whenever a visitors enters http://server, he/she is automatically redirected to http://server/index.php/Main_Page, and "Main_Page" is displayed.
Is it possible to configure Mediawiki, so that when a visitor enters http://server, he sees MainPage, but in the address bar, he still sees http://server (no, no frames etc., just display "Main_Page" when someone enters http://server)?
