ritchie93,
No, not every variation of the pages on your website.. just the 'root' of your website. That's usually just your domain name. So, if you're site is ours (sourcecoast.com), you may need all of the following:
http://sourcecoast.com/index.php
https://sourcecoast.com/index.php
http://www.sourcecoast.com/index.php
https://www.sourcecoast.com/index.php
That covers *all* pages on our site.
If you have your Joomla installation in a subdirectory of your domain, you should use that as the root. So, for example.com/joomla you'd use:
http://example.com/joomla/index.php
https://example.com/joomla/index.php
http://www.example.com/joomla/index.php
httpw://www.example.com/joomla/index.php
Finally, if you redirect all requests to www (or non-www), then you don't have to put both variations in. Just choose the one your site actually uses. Same for http vs https (though you should always have https as an option)
I hope that helps explain,
Alex
