Earlier quoted context omitted.
I was surprised it was that hard to change a route on autotrader. The article kept mentioning hundreds of thousands of pages, like they had some person editing each page in textmate.
Maybe Autotrader has hundreds of thousands of template, CSS, and JS files with those paths hardcoded. Imagine the hell it would be to work on that website. Even so, you could fix everything with a one line Perl command.
Please.
