I am setting up a simple ecommerce site. The site is live on a lunarpages server, and I need to set up the e commerce part. I will use paypal, but if I want to customize the payment page with my logo instead of Paypals, there will be
message telling the buyer the page may be "insecure"
So, to fix this I need to be on a secure SSL.  I think the paypal  code is all HTML so I think it should work on a shared SSL server.

If this is true, how do I move my site from the server its on now to a secure SSL server?

Is it as simple as changing my FTP info to https://secure(server name).lunarpages.com/~username/ and uploading my site there?
Thanks   

The url for your pages secured on the shared SSL certificate would be https://secure.yourserver.lunarpages.com/~username/page.html or https://secure.yourserver.lunarservers.com/~username/page.html
https://secure.yourserver.lunarmania.com/~username/page.html (replace yourserver with the name of your server and user with your username. Which URL to use depends on the server you are on.)

Please Note the following:

1. Shared SSL will not function with ASP, JSP or PHP pages. It will function only with html, and cgi/perl based documents/scripts/carts. This is due to security restrictions on the servers.

2. Shared SSL is not available with Lunarpages' Windows hosting plan.

Hope that helps!

Yes, I believe so.
