title: Re-direct a Subdomain to subdomain.domain.com/mypage.html
body: <p>I've searched for a similar question but can't quite find an exact match to what I need.</p>
  
  <p>I have a wildcard subdomain setup and I'd like to redirect all visitors to
  anysubdomainhere.maindomain.com to anysubdomainhere.maindomain.com/mypage.html</p>
  
  <p>I'd also like all visitors that visit without the subdomain prefix to act as normal.</p>
  
  <p>I have the following in my htaccess but I'm getting an error "too many redirects" in the browser.</p>
  
  <pre><code>RewriteCond %{HTTP_HOST} ^([^/.]+)\.maindomain\.com$ 
  RewriteCond %1 !^(www|ftp|mail)$ [NC]
  RewriteRule (.+)$ "http://%1.maindomain.com/mypage.html" [L,P]
  </code></pre>
  
  <p>Any help would be much appreciated.</p>
