A new feature in the v6 beta of Scrutiny (from v6.0.2) is the ability to trace all the redirects of the http request / response.
If a url is redirected, it is usually redirected once but it can be two or more times. In these cases, a button will be available beside the 'redirect url' field of the link inspector. The button will display the number of redirects.
Pressing the button triggers a new request to be sent and a trace will be shown showing all of the redirects as they happen and the status codes.
Download the latest Scrutiny beta. (not recommended for existing production users - please wait until v6 moves to stable.)
