Subdomain https www to non-www
<p>I have a domain called <code>example.com</code> and within this domain are two sub-domains called:</p>

<ul>
<li><code>qa1.example.com</code></li>
<li><code>qa2.example.com</code></li>
</ul>

<p>All of which have SSL certification. However, I have a <code>.htaccess</code> file as follows:</p>

<h2>UPDATED</h2>

<pre><code>Options +FollowSymlinks

Options -Indexes

&lt;FilesMatch "\.(tpl|ini|log|xml)"&gt;
 Order deny,allow
 Deny from all
&lt;/FilesMatch&gt;

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css)
RewriteRule ^([^?]*) index.php?route=$1 [L,QSA]
RewriteCond %{HTTPS} !=on
RewriteRule %{HTTP_HOST} ^www\.
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteBase /
RewriteRule ^sitemap.xml$ index.php?route=feed/google_sitemap [L]
RewriteRule ^googlebase.xml$ index.php?route=feed/google_base [L]
RewriteRule ^download/(.*) /index.php?route=error/not_found [L]
</code></pre>

<p>The following happens:</p>

<ol>
<li><code>http://qa1.example.com</code> > redirects to > <code>https://qa1.example.com</code></li>
<li><code>http://www.qa1.example.com</code> > redirects to > <code>https://www.qa1.example.com</code></li>
<li><code>https://www.qa1.example.com</code> > redirects to > <code>https://www.qa1.example.com</code></li>
</ol>

<p>Number 1 is correct, but numbers 2 and 3 need to redirect to <code>https://qa1.example.com</code> without the <code>www</code>.</p>

<p>How can this be achieved? I can include the <code>.htaccess</code> file separately for the two sub-domains.</p>
