Canonical Example

A canonical tag (aka “rel canonical”) is a way of telling search engines that a specific URL represents the master copy of a page. Using the canonical tag prevents problems caused by identical or “duplicate” content appearing on multiple URLs.

HTTP 307 Temporary Redirect – On this occasion, the request should be repeated with another URI, but future requests can still use the original URI. Unlike 302 Redirect, the request method should not be changed when reissuing the original request. For instance, a POST request must be repeated using another POST request.

A vision on http 301 redirection

The HTTP response status code 301 Moved Permanently is used for permanent URL redirection, meaning current links or records using the URL that the response is received for should be updated. The new URL should be provided in the Location field included with the response. The 301 redirect is considered a best practice for upgrading users from HTTP to HTTPS.
