How to implement a subdomain redirect to a site section via .htaccess?

Question

Apache HTTP Server

It is necessary to make sure that when visiting user.example.com, the page example.com/user opens, but not just redirects to this address, but that the subdomain address remains in the browser.

Answer 1

I do this, but the address in the browser changes to site.com/user
RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_HOST} ^user.site.com [NC]
RewriteRule ^/(.*)$ /user/$1 [L]

Answer 2

And it is impossible to configure virtual host normally?

Answer 3

I did this, placed the rule at the root:

RewriteEngine on
    RewriteBase /
    RewriteCond %{HTTP_HOST} ^coffee.
    RewriteRule ^(.*)$ /projects/coffee/www/$1 [L]

And in the folder /projects/coffee/www/ put the rule:

RewriteEngine on
RewriteRule ^$                        index.php  [L]
RewriteCond %{REQUEST_FILENAME}       !-f
RewriteCond %{REQUEST_FILENAME}       !-d
RewriteRule (.*)                      index.php?id=$1  [QSA,L]

Answer 4

I did it like this, you put the necessary directories in the subdomains directory, and the request from the subdomains goes to the appropriate one.

<IfModule mod_rewrite.c>
  RewriteEngine on

  # Subdomains
  RewriteCond %{REQUEST_URI} !^/subdomains
  RewriteCond %{HTTP_HOST} ^(.*)\.domain\.ru$
  RewriteRule ^(.*)$ /subdomains/%1/$1 [L,QSA]
</IfModule>
