Disable Split Tunnel but allow limited internet access to connect to hotel WIFI

[jall777]

Hi All.   We are running Forticlient VPN 5.6 for remote access.   We would like to disable split tunneling,  but allow travelling laptop users to connect to hotel/airport etc. WIFI in order to connect to the VPN.   Many of these WIFIs require registration on a public internet website.    On other VPN products I've been able to permit a maximum of HTTP requests  (maybe 5 to account for some redirects) over the public internet before forcing all traffic through the VPN client and thus the company firewall.      

What is the  best way to accomplish this with Fortigate/Forticlient ?
