subdomain redirect in httpd.conf?

Hello, Im trying to find out what i need to add to httpd.conf to perform a redirect in the scenario below:

I want anyone who visits https://mysubdomain.mydomain.com to be redirected to https://myserverhostname.mydomain.com:7392

Please note that it must only redirect the subdomain when using https, as http should be handled normally (which is owned by a users cPanel account).

It is important that I add (or include) to httpd.conf, and not do it through the users cpanel.

also, correct me if i am wrong but i believe i cannot use a RewriteRule because it will throw errors with the SSL certificate?

Thanks so much for reading this post.
