Get subdomain as a GET parameter

Question

Basically I have this htaccess:

Options +FollowSymLinks
Options -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ([a-z0-9-]+).([a-z0-9-]+)([/admin])? [NC]
RewriteRule ^$ index.php?domainusr=%1 [L]

Imagine that the subdomain will be a User, and I want to get that user. But the thing is this htaccess will work, with some drawbacks:

If I access something like: "http://username.domain.com/" it will work.
If I access "http://username.domain.com/index.php" it will not.
If I access any other urls than "http://username.domain.com/", like: "http://username.domain.com/admin/", "http://username.domain.com/front/index.php", it won't work.

My question is: How can I have this subdomain as a GET parameter in EVERY accessable content, without interfering with others GETs?

Not a solution but a proposal: why not using something like [this](http://stackoverflow.com/questions/5292937/php-function-to-get-the-subdomain-of-a-url#answer-11127956) to get the subdomain instead of adding a GET parameter? — Christian Fries, Nov 24 '14 at 12:07
It will indeed work, but I really wanted to see a solution using mod-rewrite. But thanks! — Nilton Frederico Teixeira, Nov 24 '14 at 12:17

If you want to add ?domainusr=%1 to all your links, with this .htaccess:

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ([a-z0-9-]+)\.domain\.com [NC]
RewriteRule ^(.*)$ $1?domainusr=%1 [QSA,L]
