10.3 and 3.1 HTTP to HTTPS Redirect Not Working on Web Server
Problem
We have an SSL certificate generated and imported into our web server. I know we need to redirect HTTP to HTTPS in IIS7. After following the basic instructions, it redirects fine in Firefox & Chrome, but we get a 403 Forbidden error when you try to get an HTTP to HTTPS redirect in IE.
Solution
Research found that it couldn't redirect because of an Internet Explorer setting called 'Friendly Messages'. If you pad your custom redirect message in your redirect.html file with at least 5-10 lines of spacing after the redirect message and then save it, it redirects fine when you hit the HTTP URL.
