Check canonicalization work implemented on URL

[McTaggart]

Hi I was wondering how to check canonicalization when it's not working properly - I am getting redirect from http://www to www but not from non www version to www version of URL) - so, how do I check the type of redirect in place already in the URL? Is there a tool for testing this? Thanks, Luke

I like Ayima's Chrome extension "Redirect Path."

When you go to a page, just click it and it will tell you all the URLs you visited on the way there and what the http status codes are for each. Nice.

Hi Luke

This tool (http://www.tomanthony.co.uk/tools/bulk-http-header-compare/) will be able to give you the response code each URL is sending, allowing you to see if it is set up correctly.  If anything is wrong, however, it won't say why it's returning that response instead of the desired one.

Hope this helps.
