Notice: Undefined index: HTTP_REFERER

Hi,

I'm working on a local installation and I get the following message:

Notice: Undefined index: HTTP_REFERER in my/drupal/folder/modules/ip2locale/ip2locale.module on line 140

I suggest to replace line 140 with the following:

if (!isset($_SERVER['HTTP_REFERER']) || (isset($_SERVER['HTTP_REFERER']) && strpos($_SERVER['HTTP_REFERER'], $_SERVER['SERVER_NAME']))) return FALSE;
