If you've configured SSL for one of our custom domains, you may want to ensure that all visitors to your site are forced onto a secure connection. Usually, you could just do this from within your application itself however you can now just tick a box in myViaduct and we'll do it for you.
If you want to redirect all users from http:// to https:// URLs, you can simply head over to the settings page for any custom domain and check the Force SSL checkbox. Once checked, any GET request received without SSL will be redirected to the SSL version of the page.
This should be combined with HSTS to ensure that your site is secure. For now, you would need to add the HSTS headers in your application.
