Auto subdomain with mod_rewrite

[Ozz]

I want to make script based subdomains without adding from cpanel.
I mean:
www.domain.com/user.php?name=ozz
address invisibly redirects to:
ozz.domain.com
I did so many tries on htaccess with mod_rewrite and some changes httpd configuration made wildcard enabled but every subdomains goes to my domain's main index page.
Can you help me whats wrong with that?

I cant place a support ticket I only think maybe someone needed it too or made it.

I haven't written a rewrite for a while.

In the most simple case I would use something like this.

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.com$
RewriteRule ^(.*)$ /user.php?name=%1 [L]

I would suggest you post your rewrite script here so we can look at it an pick it apart.

If you haven't included the Options +FollowSymLinks line then I would include it. (Dunno if symlinks is on or off by default, but it never hurts to make sure?)

That gives 503 error on all pages VangariDei.
I use this htaccess:

<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^\.htaccess$ - [F]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^tag/(.*)/$ search.php?fields=link&q=$1
RewriteRule ^tag/(.*)$ search.php?fields=link&q=$1
</IfModule>

I put yours after RewriteEngine on:

RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.com$
RewriteRule ^(.*)$ /user.php?name=%1 [L]

And give Internal Server Error on all pages

Ozz just one question:

You said you want it to invisbly redirect to ozz.domain.com. Do you mean that you want www.domain.com/user.php?name=ozz to keep appearing in the browser's address?

Because if not, you could use a simple PHP script like:

<?
header("Location: http://$name.domain.com");
?>

Well I dont want to long url shown in address bar, user types ozz.domain.com address bar must stay ozz.domain.com. I mean that, as invisible.
