Guys robots_ssl.txt or robots.txt?

Question

Search Engine Optimization

There is such a websiteauditor software that says that a site with a secure protocol should have a document of the form: robots_ssl.txt and so I haven’t seen anything like this anywhere in the recommendations, someone can give a link or shed some light.
PS I even use the good old robots.txt on https and everything works fine!

Answer 1

There are situations when the secure https protocol is used only for certain pages on the site (usually a contact form, an order form, and other pages where users can enter personal data).
To close such pages from indexing, they make a separate version of the instructions, which will be available via a secure protocol.
Create a robots_ssl.txt file (you can use any file name) and configure the server settings so that when you request https://domain.com/robots.txt file opens.
To do this, the necessary parameters are written in .htaccess:

RewriteEngine on 
Options +FollowSymlinks 
RewriteCond %{SERVER_PORT} ^443$ 
RewriteRule ^robots.txt$ robots_ssl.txt

Port 443 is used for secure connections instead of the standard 80.
