How to solve the problem with dynamic subdomains?

Question

Yii

The situation is this, the site has a bunch of dynamic subdomains, like username.site.com, they are all processed by one yii application using mod_rewrite:

RewriteCond %{HTTP_HOST} ^(www\.)?([^\.]+)\.site\.com$ [NC]
RewriteRule (.*) index.php?un=%2 [NC,QSA]

Everything would be fine, but being on a subdomain, when accessing any other script other than index.php, no access occurs.
For example: if you click on the link alien.site.com/go.php when you are on alien.site.com, you will access index.php, as well as with any other scripts. How to fix it?

Answer 1

A couple of years ago, a similar question was asked on the Russian-language yii forum. I described the solution to a similar problem in this topic .
Briefly
apache virtualhost settings:

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot "D:/Projects/WWW/urlShortener"
    ServerName urlshortener.localdomain
    ServerAlias *.urlshortener.localdomain
    ErrorLog "logs/urlShortener.localdomain-error.log"
    CustomLog "logs/urlShortener.localdomain-access.log" common

    <Directory />
        DirectoryIndex index.php
    </Directory>
</VirtualHost>

mod_rewrite:

RewriteEngine on

# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# otherwise forward it to index.php
RewriteRule . index.php

as well as CUrlManager rules:

array(
    'http://<user:\w+>.example.com/<lang:\w+>/profile' => 'user/profile',
)

This is how my subdomains work

RewriteCond %{REQUEST_URI} !^/
RewriteRule ^(www\.)?([a-zA-Z0-9_/\-]*)\.site\.com(.*) /$2/%{REQUEST_URI} [L]
RewriteRule ^([a-zA-Z0-9_/\-]*)$ index.php
