Detect broken links in Codeigniter

Do you开发者_运维百科 know any script to detect broken links in a site developed in codeigniter (with url rewriting)? Thank you

I have used Xenu's Link Sleuth in the past. You give it a URL and it will crawl the site looking for broken links. I'm not entirely sure if this is what the question is after though. Could you clarify please?
