title: Remove facebook URL parameters via .htaccess
body: <p>On my website i have facebook comment form. So, when some user answered on facebook comment, comment's author receives message with link looks like <code>http://somesite/?p=650336994452395724_787132&amp;fb_comment_id=fbc_206901222839669_334304_206901256172999#f2c762c5d4</code> but comments avaiable only by <code>http://somesite/?p=650336994452395724_787132</code> url.</p>
  
  <p>So, i need to remove all parameters after <code>http://somesite/?p=650336994452395724_787132</code> by .htaccess. I've tried to do that with next code 
  <code>RewriteCond %{QUERY_STRING} fb_comment_id=.*$
  RewriteRule .* %{REQUEST_URI}? [R=301,L]</code> 
  but it gives me wrong url.</p>
