title: how to force drupal function to not use DB cache?
body: <p>i have a module and i am using <strong>node_load(array('nid' => arg(1)));</strong>
  now the problem is that this function keep getting its data for node_load from DB cache.<br>
  how can i force this function to not use DB cache?<br>
  <strong>Example</strong><br>
  my link is <a href="http://mydomain.com/node/344983" rel="nofollow">http://mydomain.com/node/344983</a><br>
  now:<br>
      $node=node_load(array('nid'=>arg(1)),null,true);<br>
      echo $node->nid . " -- " arg(1);<br>
  <strong>output</strong><br>
  <em>435632 -- 435632</em><br>
  which is a randomly node id (available on the system)<br>
  and everytime i ctrl+F5 my browser i get new nid!!  </p>
  
  <p>Thanks for your help</p>
