Which module in Drupal saves the GET parameters of a visit?

Question

Drupal

Please tell me a module for D6 that does one of two things:
1) Either allows you to save the GET parameters with which the user came to the site during his visit and access them as needed
2) Or builds on the Statistics module and writes GET parameters to the visit log (not just a URL with no parameters)
I'm primarily interested in storing UTM tags during the visit to send them along with the webform.

Answer 1

if (!isset($_COOKIE['Drupal_visitor_get'])) {
  user_cookie_save(array('get'=> serialize($_GET)));
}
