I have a website (built with MediaWiki 1.33.0 CMS) which contains a robots.txt file.
In that file there is one line containing the literal domain of that site:
I usually prefer to replace literal domain referrals with a variable value call that will somehow (depends on the specific case) will be changed in execution to the value which is the domain itself.
An example to a VVC would be a Bash variable substitution.
Many CMSs have a global directives file which usually contains the base address of the website:
In MediaWiki 1.33.0 this file is
LocalSettings.php which contains the base address in line 32:
$wgServer = "https://example.com";
How could I call this value with a variable value call in robots.txt?
This will help me avoid confusion and malfunction if the domain of the website is changed; I wouldn’t have to change the value manually there as well.
