This tool will check your server headers and the HTTP result codes it returns. It will follow any redirects it finds along the way, whenever possible. With this tool you can check to see how your server is redirecting and if your server is returning 404 for URLs which do not exist.

Checks for redirects on a domain

The redirect check tool looks at a number of different URLs for your homepage, and reports back on the response code given by each. To be completely safe, a 200 response should only be returned by one page. Other pages should return a 404 or 301. Anything else could be a potential duplicate content problem.
