title: .htaccess redirect all pages except the home page
body: <p>I have just merged two websites. Site A is now merged with site B.</p>
  
  <p>Site A has got a .htaccess file which redirects all of the content to the new domain where site B is hosted. </p>
  
  <pre><code>RewriteRule (.*) http://www.siteb.com/$1 [R=301,L]
  </code></pre>
  
  <p>It is working perfectly, however, I need the homepage of site A not to redirect.</p>
  
  <p>What do I need to add to the code above to make that happen?</p>
