Bypass application.cfm login for a certain page

I have a member website that requires login. The Application.cfm file is in the root folder. I have the "register" page hosted on a separate website with a different host. (I am in the process of migrating the member website from the current server/host to a new server/host). I plan to keep the public side of the current/old website for marketing purposes and to register new members. Only problem is, I now have to figure out how to get the newly registered members' information into the MySQL database housed on the new server that is password protected at the root folder. I can't get past the login page to run the .cfm page that will insert the info into the database.

I thought about using a PHP or ASP script to insert the data, but I am not at all familiar with either languages, especially how to encrypt the password for the newly registered account (the equivalent to "#Hash(password)#").

So, I'm wondering if there is any way to allow a certain page to be exempt from login. Or, find out if anyone has any other ideas that may work.

I'm on a shared server with CF9 and Windows.

Thank you for any suggestions.
