I have sometimes a problem that the browser redirect the url a lot of double urls.
When I enter example.com then the browser redirect to https://www.example.com
Pass

One problem is that google find this with index.php then double content, why?
https://www.example.com – double content with – https://www.example.com/index.php

The next problem is that sometimes the url index.php redirect moretimes.
htts://www.example.com/index.phpindex.phpindex.phpindex.phpindex.phpindex.phpindex.php…
Why this?
