How to properly implement cnc links in .htaccess?

Question

PHP

Hello everyone, how to properly implement cnc links using .htaccess?

There is a link
/?gr_id_off=665 and /?gr_id_on=999
it was necessary to get saite.ru/delete/off/665
and accordingly saite.ru/add/on/999

did this:

RewriteRule ^add/vkgrup/([^/\.]+)/?$ ?gr_id_off=$1 [L]
RewriteRule ^delete/vkgrup/([^/\.]+)/?$ ?gr_id_on=$1 [L]

It seems to work, I don’t know if it’s free, the second question is:

How to make from /?mailing=1 and /?balance=1

:
saite.ru/mailing.html
saite.ru/balance.html

Answer 1

RewriteRule ^mailing\.html$ /index.php?mailing=1 [L]
RewriteRule ^balance\.html$ /index.php?balance=1 [L]
