The server is fooling you!!!

Actually yea kazer0 is right. The mod uses htaccess URL redirection, basically works like this:
When the server sees a URL ending in like posting-nc-mode-reply-t-2813.html (the URL for this post) it matches a regular expression in a list in the htaccess file. It then reinterprets the URL and displays a different page. The trick is that search engines just see the .html URL, not the "real" URL. This is important because if a SE is surfing, say, .php URLs, like view.php?num=9&page=101 it will stop after a certain # of pages ... whereas with html files it will continue capturing pages until it finds 'em all. At least, that's how it was explained to me
A sample line from the htaccess file looks like:
RewriteRule ^([^/]+)-nc\-([^-]+)\-([^-]+)\-([^-]+)\-([^-]+).html $1.php?$2=$3&$4=$5 [L]
I know how to write a htaccess file but I didn't do this mod ... that kinda stuff is a bit beyond my technical prowess atm.
