Two questions from beginner

[virus.do.201041]

Good day!

I am a novice user on your system, I have two very interesting question to me:

1) ". Htaccess" not working for you, although on a home server, everything is fine. Please tell me how to use his work?

File Example:

 RewriteEngine on
 RewriteBase /

 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteRule ^(.*)$ index.php?Action=Page&query=$1 [L]

Example script:

 <?
    var_dump($_REQEST);
 ?>

As you can see all the elementary, purely for testing, but does not work (

2) I have a domain for hosting this, I want to create a subdomain. Advice please NS server!

Thanks in advance! =)
