title: Rename session cookie to something else, than PHPSESSID
body: <p>I am reading through the suggested php.ini changes from <a href="https://github.com/h5bp/html5-boilerplate/blob/master/.htaccess" rel="nofollow">https://github.com/h5bp/html5-boilerplate/blob/master/.htaccess</a></p>
  
  <p>One of the suggestions is:</p>
  
  <pre><code># Rename session cookie to something else, than PHPSESSID
  php_value session.name sid
  </code></pre>
  
  <p>I am interested to know how this could effect my current websites and how this would improve security?</p>
