Many of my url's on my site www.mysite.com/Display.aspx?ID=128

gets displayed to users as

www.mysite.com/Display.aspx?ID=128&AspxAutoDetectCookieSupport=1

How can I remove AspxAutoDetectCookieSupport.

I understand it has to do something with cookie in web.config, but where? And what would be the implications if I remove that. How to remove?
