Need to redirect http to https

Hi, we have a site, seniormealsolutions.com, which for reasons I won't go into doesn't yet have an SSL certificate.

if you go to the http version, you get the proper site.

If you go to the https:// version, you see our main site, magickitchen.com, but with the seniormealsolutions.com still in the address window. I am worried that this will show to Google as duplicate content, would it?

I've tried various ways to redirect https to http, in .htaccess, with no success so far. here's what I've tried:

RewriteEngine on
RewriteCond %{HTTPS} on
RewriteRule ^/?$ http://%{SERVER_NAME}/ [R=301]
RewriteRule ^inner/directory/?$ http://%{SERVER_NAME}/inner/directory/ [R=301,L]

Select allOpen in new window

RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} =https
RewriteRule ^(.*)$ http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Select allOpen in new window

<VirtualHost *:443>
  SSLEnable

  RewriteEngine On
  RewriteCond %{HTTPS} on
  RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI}

</VirtualHost>

Select allOpen in new window

RewriteEngine On
RewriteCond %{SERVER_PORT} 443
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Select allOpen in new window

RewriteEngine On
RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
