rewriteRule simple problem

[robert_gsfame]

I have created subdomain for user and all will be redirected to page.php

The problem is that when there is a special character in the subdomain let say

 

da-vinci.mydomain.com then i have this on the url da-vinci.mydomain.com/page.php?user=da-vinci

 

I wish to hide page.php?user=da-vinci

How can i do this??

Below is my .htaccess code

 

<IfModule mod_rewrite.c>

Options +FollowSymLinks

Options +Indexes

RewriteEngine On

RewriteBase /

RewriteCond %{HTTP_HOST} !www.mydomain.com$ [NC]

RewriteCond %{HTTP_HOST} ^([a-z0-9-]+).mydomain.com [NC]

RewriteRule (.*) page.php?user=%1 [L]

</IfModule>

 

I am really newbie on this

THX for any helps!!
