title: Session Conflicts codeIgnite (2 applications within same server using auth_tank library)
body: <p>I have 2 applications running at same server. When I am using one application and logging in inside it. It is working fine.
  But when I access an other application from same server withing same browser. and logging in that 2nd application. Both of the applications logout. I am not able to do anything more after logging in both applications at same browser.</p>
  
  <p>What I have tried I am giving you details below:
  1. Have changed session variable names.
  2. Even I have used another external session library that is <a href="https://github.com/bcit-ci/CodeIgniter/wiki/Dariusz-Debowczyk" rel="nofollow">https://github.com/bcit-ci/CodeIgniter/wiki/Dariusz-Debowczyk</a>'s-Session-Class
  and I have also changed </p>
  
  <pre><code>$config['sess_cookie_name']     = 'ci_session'; 
  </code></pre>
  
  <p>to </p>
  
  <pre><code>$config['sess_cookie_name']     = 'session';
  </code></pre>
  
  <p>This is session config in config.php</p>
  
  <pre><code>$config['sess_expiration']      = 7200;
  $config['sess_expire_on_close'] = FALSE;
  $config['sess_encrypt_cookie']  = FALSE;
  $config['sess_use_database']    = TRUE;
  $config['sess_table_name']      = 'ci_sessions';
  $config['sess_match_ip']        = FALSE;
  $config['sess_match_useragent'] = TRUE;
  $config['sess_time_to_update']  = 300;
  </code></pre>
