Thank you for your reply Dave.
I explain little further: I presume that my site www.kimwist.com should redirect to http when attamted to access via https, because I don't have a SSL certificate for the site.
However, https takes to a page the server administration has set up, that says my site will be shown here in the near future. This is just like I just purchased the domain and have not uploaded any site to it yet.
I should probably contact the host provider and ask about this, but I also read that this is a common problem and should be fixed with the "rel canonical tag" in .htaccess file, that is the reason I asked about it here.
The .htaccess code that you provided shuts the server and creates an internal error, so something else should be implemented.
The whole issue is of course because https is considered duplicate content and I simply want https to redirect to http, but it seems to be quite difficult to accomplish.
Thanks, Kim
