And you could write a server-side test that performed a simple interaction via http or https and inspected the result more deeply than just the success of something (not an HTTP error code) being returned.
The in-built http(s) test can also check the content of a specific page. For my use case, I check the page contains one of the css classes generated by the CMS, which I interpet as confirmation that not only is there something responding with HTTP 200, but the CMS is generating "sane" HTML. There are some other possibilities for the HTTP test too:

and so the relevant lines in my hosts.cfg for what I described above are e.g.
1.2.3.4 www.example.com # cont;https://www.example.com/;"my-css-class";
