Pre-requisite

When the user is presented with a disclaimer page and selects the ‘Yes, I agree’ button, the administrator wants to present a new web page to the user. (Example: the organization’s internal website).

This can be done by editing the source code of the disclaimer page.

From GUI, Go to System -> Replacement Messages -> Extended View -> Authentication -> Disclaimer Page, ‘double-click’ or select ‘Edit‘, and add the below code to the function sb(val):

if(val == '1'){
window.open("https://www.example.com");
}

Replace www.example.com to the desired website by the administrator. See the below screenshot:
