Mobile Device Detection with logic

I choose to go to the full site by clicking a hyperlink on the mobile site (www.site.com/?mobile=false) then redirect back to www.site.com and exit from further processing.i think the problem is here since after redirection, browser may create a brand new connection to www virtual server and it will be redirected to mobile virtual server again. local variable is not shared across connection. for global variable, i am not sure what data we can use. ip address might not be a good idea because mobile device may be behind nat device. cookie is not an option as you mentioned it is not supported on all device.

 

 

the rule above i used different FQDN in url (e.g. www2.site.com/?mobile=false), so we will be able to detect it later.
