title: htaccess redirect dynamic urls
body: <p>I am trying to write a htaccess redirect, but it is not working as I want it to.
  My current (working) htaccess redirects all html pages with 1 character to the index file as:</p>
  
  <pre><code>RewriteRule ^([a-zA-Z0-9]).html$ index.php?letter=$1
  </code></pre>
  
  <p>So a.html gets redirected to index.php?letter=a
  Now I need to redirect the page a.html?page=2 to index.php?letter=a&amp;page=2
  Basically I want to redirect the url, but leave the dynamic part intact.
  All of the following return a 404: </p>
  
  <pre><code>RewriteRule ^([a-zA-Z0-9]).html?page=([0-9]+) index.php?letter=$1&amp;page=$2
  
  RewriteRule ^([a-zA-Z0-9]).html?page=(.*) index.php?letter=$1&amp;page=$2
  
  RewriteCond %{QUERY_STRING} page=(.*)
  RewriteRule ^([a-zA-Z0-9]).html(.*) index.php?letter=$1&amp;page=%1
  </code></pre>
  
  <p>I think I'm close, but I can't seem to get there :/ 
  could anyone give me the last push?</p>
