How to implement the issuance of a specific robots.txt for all subdomains by *.mysite.ru mask?

Question

linux

There are many technical subdomains on which it is necessary to close access to search engines. All domains fall under the mask *.mysite.ru
Can all clients accessing *. mysite.ru/robots.txt issue a redirect to some pre-prepared file on a static path? for example, https://mysite.ru/no-robots.txt

Or do you have to manually edit the configs for each host?

Answer 1

You can make a config that will process all subdomains - server_nameit also supports regular expressions. There your prohibiting robots.txt and add.
