Как подружить .htaccess файл для популярных CMS с Nginx

Начну с небольшого вступления: зачем вообще нужен .htaccess файл? .htaccess — это конфигурационный файл, который использует веб‑сервер Apache для задания специфических настроек для каждой отдельной папки сайта. Благодаря ему можно:

Apache #mod_rewrite rule to stop bots from scraping your content:

# Deny bots
RewriteCond %{HTTP_USER_AGENT} "[Bb]ot/|meta-externalagent|Chrome/1[^34]|Chrome[02-9]"
RewriteRule .* - [G]

The Chrome terms catch obsolete version numbers that the bots seem to use.

#nobots

Can someone please explain to me why an Apache mod_rewrite rule would apply in Chrome, but not in Firefox? Basically, I'm taking the requested subdomain, e.g. [something].mywebsite.com, and using that string to 301 redirect to mywebsite.com/[something]. Works perfectly in Chrome, but hasn't worked in Firefox in a while (first version worked in both, but I had to reimplement it after a WordPress update overwrote it) and I have no idea why that should be a thing. We basically have zero Firefox users attempting to use the subdomain aside from myself, so it doesn't *really* matter, but I just want to understand (and avoid an unnecessary customer service email in the event that a Firefox user scans the QR code and erroneously ends up at the homepage; yes, the subdomain was a mistake. But the QR codes are out there by the thousands, so it's too late for me now lol).

I should say that the majority of my mod_rewrite experience was probably a decade or so ago, so I'm definitely pretty rusty.

The rule:

RewriteCond %{HTTP_HOST} ^(?!www\.)([^.]+)\.(mywebsite\.com)$ [NC]
RewriteRule ^ http://%2/%1%{REQUEST_URI} [L,R=301,NE]

#apache #mod_rewrite #server

So this should get rid of the bots:

# Deny bots
RewriteCond %{HTTP_USER_AGENT} "[Bb]ot/|meta-externalagent"
RewriteRule .* - [G]

#apache #mod_rewrite
