Where did the wiki/mod_rewrite page go?

This tutorial video from March 2012:
http://www.youtube.com/watch?v=dynPx1B0jis

shows a page at URL:
http://codeigniter.com/wiki/mod_rewrite

(at about 5 mins in) which no longer exists. It appears to have some different mod_write settings to what I can find in the forums (eg http://ellislab.com/forums/viewthread/119491/), and I can't see a page in the wiki about it.

Straining my eyes at the text in the tutorial video, it appears to have these lines added:
RewriteCond %{REQUEST_URI} ^application.*
RewriteRule ^(.*)$ /index.php/$1 [L]

Can anyone tell me why the wiki page is gone, as I've wasted a lot of time trying to understand the settings I need to use. Thanks!
