How to set up multidomain in .htcaccess?

Question

Apache HTTP Server

In general, there are domains omsk.site.ru, tomsk.site.ru, etc. They all have the same files with different domain generation through sql database. Each domain in its own folder.
In general, how to make all domains access the same file and generate their content? At the same time, new domains will be formed in the future, and you need to register in .htcaccess once.

Answer 1

What's the problem? In htaccess, you can generally not use a domain, otherwise everything will work.
It's not entirely clear from the question: do you want one set of scripts to give data depending on the domain?
If so, then the issue is not htacess. Define the domain in the script and make selections and output based on this.
