title: .htaccess remove numbers and extension from URL string
body: <p>I'm doing some reverse proxies for a blog and would like to achieve the following in my .htaccess file.</p>
  
  <p><strong>Redirect Legacy URLs</strong></p>
  
  <p><a href="http://blog.domain.com/post-title-123.html" rel="nofollow">http://blog.domain.com/post-title-123.html</a></p>
  
  <p>to</p>
  
  <p><a href="http://blog.domain.com/post-title/" rel="nofollow">http://blog.domain.com/post-title/</a></p>
  
  <p>I think I have to use the following piece of regex -[0-9]+.html to identify the part of the URL I wanted 'changing' to a /.</p>
  
  <p>Any suggestions?</p>
