Cookies >>>
Redirects the visitor to different pages based on the value of a stored cookie. If no cookie is found, the available items are displayed for the user to pick from, which sets a cookie for their next visit. Our demonstration uses a 'favorite animal' cookie, but this could easily be modified to fit your needs.
Add the below code to the <body> section of your page:
