I am rewriting a subdomain URL with a query (cart.example.net/ProductDetail.jsp?LISTID=7C0400-1101763508) to a www subdomain (www.example.net/product-category/product).The problem I am facing is the URL link doesn't have the http:// (eg. cart.example.net) and that is going to a 404 on the server (not a 404 on the website). That isn't happening on subdomain links that have the http already (eg. http://cart.example.net).  I believe the solution is to add the http in .htaccess if that is possible. Any help on adding the http:// in .htaccess or any other possible solution is greatly appreciated!
