HTTPs check function was available via CgiCC library, but its implementation 
is Apache specific. See: http://httpd.apache.org/docs/2.0/mod/mod_ssl.html

What this function does, it checks that HTTPS environment variable is set
or (under Windows) it is set to "ON".

This is generally not correct solution and should not be used in portable
software.

You may use getenv but you should understand that this is Apache specific.

The only portable way I think you can do this is to check server_port()==431
or other predefined value that you know that web server uses for https protocol. 


But as you understand this require from the developer to be aware of web server 
port.
You may just put it into you configuration and check like this:

   if(server_port() == 
settings().get<int>("my_application.web_servers_https_port")) {
      // we on https
   }

So, this CgiCC "feature" is rather "bug" as its implementation is incorrect and 
may mislead you.
