How include hash (#) in drupal_goto path? Is there any way to include a # in drupal_goto?

i want something like this

function MYMODULE_preprocess_node(&amp;$variables) {
  $node = $variables['node'];
  switch ($node-&gt;type) {
    case 'product':      
      drupal_goto("products#".$node-&gt;nid);
  }
}
For Drupal 6,

It should be 3rd parameter 

drupal_goto($path = '', $query = NULL, $fragment = NULL, $http_response_code = 302)

drupal_goto("products", NULL, $node-&gt;nid);


For Drupal 7

drupal_goto($path = '', array $options = array(), $http_response_code = 302)
drupal_goto("products", array('fragment' =&gt; $node-&gt;nid));
