url redirection issue using .htaccess - php

Question

Below are the things i need to convert using .htaccess
If url is sample.xxx.com means i need to convert it to www.xxx.com/domain/sample
I url is sample.xxx.com/category/34/electonics.html means i need to convert it to www.xxx.com/domain/sample/category/34/electronics.html
3.After converting those things again i need to build request to the necessary pages
I have the following rule
RewriteEngine On
RewriteCond %{HTTP_HOST} ^([^\.]+)\.example\.com$ [NC]
RewriteCond %1 !^(www|ftp|mail)$ [NC]
RewriteRule ^(.*)$ http://www.example.com/domain/%1/$1 [P,QSA]
RewriteRule ^domain/([a-zA-Z0-9_\-]+)$ index.php?domain=$1 [Nc,L]
RewriteRule ^domain/([a-zA-Z0-9_\-]+)/$ index.php?domain=$1 [Nc,L]
RewriteRule ^domain/([a-zA-Z0-9_\-]+)/news/([a-zA-Z0-9_\-]+)/([0-9]+)_([0-9]+)/([a-zA-Z0-9_\-]+)\.html$ news.php?domain=$1&category=$4&news=$3 [Nc,L]
RewriteRule ^domain/([a-zA-Z0-9_\-]+)/category/([0-9]+)/([a-zA-Z0-9_\-]+)\.html$ category.php?domain=$1&category=$2 [Nc,L]
RewriteRule ^domain/([a-zA-Z0-9_\-]+)/gallery/([0-9]+)/([a-zA-Z0-9_\-]+)\.html$ gallery.php?domain=$1&category=$2 [Nc,L]
RewriteRule ^domain/([a-zA-Z0-9_\-]+)/video/([0-9]+)/([a-zA-Z0-9_\-]+)\.html$ video.php?domain=$1&category=$2 [Nc,L]
But it fails
If i change line 4 to
RewriteRule ^(.*)$ http://www.example.com/domain/%1/$1 [NC,QSA]
means it will work but the browser shows the reconstructed url.
Anyone spot my error please.

If you keep http:// in target URI then it will indeed be full redirect.
Try this:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^(www|ftp|mail)\. [NC]
RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com$ [NC]
RewriteRule ^((?!domain/).*)$ domain/%1/$1 [L,NC]
RewriteRule ^domain/([\w-]+)/news/([\w-]+)/([0-9]+)_([0-9]+)/([\w-]+)\.html$ news.php?domain=$1&category=$4&news=$3 [NC,L]
RewriteRule ^domain/([\w-]+)/category/([0-9]+)/([\w-]+)\.html$ category.php?domain=$1&category=$2 [NC,L]
RewriteRule ^domain/([\w-]+)/gallery/([0-9]+)/([\w-]+)\.html$ gallery.php?domain=$1&category=$2 [NC,L]
RewriteRule ^domain/([\w-]+)/video/([0-9]+)/([\w-]+)\.html$ video.php?domain=$1&category=$2 [NC,L]
RewriteRule ^domain/(.+)/?$ index.php?domain=$1 [NC,L]
