How to disable subdomain redirections in .htaccess?

Hi

Firstly, thank you for making a good cache plugin!

Here is the problem I’m having with my .htaccess file.
I have WP installed in the \public_html directory but when I try to create subdomains in the cPanel (which would be something like sub.mydomain.com as the URL and which creates directories in the public_hmtl like this: \public_html\sub), then when I try to access it in the browser, the URL is redirected to http://www.sub.mydomain.com/sub/

I figured there is a problem with my .htaccess file because when I disable the .htaccess file, the subdomains work as they should.

This is my .htaccess file:

# BEGIN WpFastestCache
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
AddDefaultCharset UTF-8
RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{REQUEST_URI} !^/wp-login.php

I’ve also tried the suggestions I found in another thread but it didn’t work for me: http://wordpress.org/support/topic/ignore-rewrite-for-subdomains
