How do I code a static path

I want to hardcode a path for my template in WP-Config. I use a parent theme with child themes that act as “skins”. Two questions:

1. Am I correct that I need to set:

define(‘TEMPLATEPATH’ to point to the folder containing the parent theme and

define(‘STYLESHEETPATH’ to point to the folder containing the child “style.css” file?

2. The syntax I have seen says that the proper way to do this is:

define(‘TEMPLATEPATH’, ‘/absolute/path/to/wp-content/themes/active-theme’);

So what constitutes the absolute path? I have tried these four:

https://mysite.domain.com/wp-content/themes/mytheme
/mysite.domain.com/wp-content/themes/mytheme
mysite.domain.com/wp-content/themes/mytheme
/wp-content/themes/mytheme

and all give me the same (incorrect) result. mysite is in a folder directly below the root of my server, and the subdomain has a CNAME alias pointing at that folder. I don’t think there are any more levels to add! The directory structure is the pure vanilla WordPress default with wp-content directory off the top folder (which is just below root) and my themes are directly wp-content.

This has to be simple; what am I missing?
