/* This code supports the ability for your website to set a cookie on behalf of MobFox
 * To set an MobFox cookie, simply call pcl_setcookie() on any page that you call pcl_request()
 * The call to pcl_setcookie() must occur before any output has been written to the page (http://www.php.net/setcookie)
 * If your mobile site uses multiple subdomains (e.g. "a.example.com" and "b.example.com"), then pass the root domain of your mobile site (e.g. "example.com") as a parameter to pcl_setcookie().
 * This will allow the MobFox cookie to be visible across subdomains
