I'm not sure how to propose this to the osC team but I figured that this was the best place to start.

I would appreciate it if any of the osC team members would let me know the proper "channels" to follow for this sort of thing.

In a recent thread a person had a problem where their domain of www.domain.co.uk was not setting the cookie.  The reason was because the tep_get_top_level_domain function was not accounting for the extra domain qualifier and returning a result of co.uk.

I have modified the function to accommodate for extra qualifiers (regardless of the number) to return the proper domain name.
[code] function tep_get_top_level_domain($url) { 
    if (strpos($url, '://')) { 
      $url = parse_url($url); 
      $url = $url['host']; 
    } 

    $domain_array = explode('.', $url); 
    $domain_size = sizeof($domain_array); 

    if ($domain_size > 1) { 
      $domain = ''; 
      for ($i = 1; $i <= $domain_size; $i++) { 
        $domain .= '.' . $domain_array[$i]; 
      } 
      if (is_numeric($domain)) { 
        return false; 
      } else { 
        return $domain; 
      } 
    } else { 
      return false; 
    } 
  }

Feel free to modify the code as you see fit.
