I am trying to find out if redirecting an https URL to an http URL will still provide the security of the original https? Should the page information for the redirected http page show it as being unencrypted or shouldn't it have the same encryption as the original https?
Since you will redirect your traffic to a non-HTTPS protocol, the traffic isn't going to be encrypted anymore. HTTPS is simply HTTP with SSL/TLS on top of it.
Here is an important piece of advice - if you're using two different addresses for your web pages, it can cause you to have one or both versions indexed in search engines and negatively affect your traffic. Be very careful with this.
