I made the suggested changes and the crawler ran fine. But, I am running into another issue. My purpose was to crawl the site to detect all the Canonical URL's on the website. I checked "enable canonical URLs" under Advanced Settings and then ran the crawler. It just gave an xml sitemap file with all the URL's it detected. I dont see a seperate coloumn which lists the canonical URL's detected. Does this tool provide the output of the Canonical Link for all the URL's that it detected?
