title: Codeigniter Sessions: ignore Wget/1.9.1
body: <p>I'm saving Codeigniter Sessions to a Database as suggested in <a href="http://codeigniter.com/user_guide/libraries/sessions.html" rel="nofollow">User Guide</a>.
  I have also some cronjobs (wget) running, some of them, every minute and my ci_sessions table gets filled with thousands of records in just a few minutes.</p>
  
  <p>I don't need or want to save session records where user_agent are Wget/1.9.1.</p>
  
  <p>Any idea how to do this? </p>
  
  <p>Thank you.</p>
